HARRISBURG, Pa. (AP) — The student protest movement disrupting university campuses, classes and graduation ceremonies over the war in Gaza is also roiling Senate contests across the nation as Democrats tread cautiously over an internal divide and Republicans play up their rivals’ disagreements.

The political impact of the protests on the White House campaign has drawn considerable attention, with opposition to President Joe Biden’s handling of the Israel-Hamas war reverberating from Columbia to UCLA. The fast-evolving landscape of the demonstrations is shaping pivotal Senate races, too.

Tent encampments have popped up at universities in many states where Democrats this election year are defending seats essential to maintaining the party’s razor-thin Senate majority. At some schools, police crackdowns and arrests have followed.

The protests have sharpened the campaign rhetoric in Pennsylvania, Nevada, Ohio and Michigan, among other places. Republican candidates in California and Florida have stepped up their criticism of the Democratic president for the U.S. response to the war or for chaotic scenes on American campuses.

Some Republicans have shown up at encampments, including one at George Washington University, not far from the White House. Sen. Rick Scott, R-Fla., who is facing reelection, said on social media that he went there to show solidarity with Jewish students. “We need to do all we can to protect them,” he said.

Republican candidate David McCormick, during a visit to the University of Pennsylvania, said protesters at the Ivy League school did not know the “difference between right and wrong, good and evil,” and were creating a hostile atmosphere for Jewish students.

McCormick has decried what he frames as a lack of leadership and moral clarity on the part of his Democratic opponent, Sen. Bob Casey, as well as by Biden and administrators at the school buffeted by accusations of harboring antisemitism.

“What’s happening on campuses is clearly a test of leadership and moral courage, both for the college presidents and for our leaders and for Sen. Casey and President Biden,” McCormick said in an interview.

Israel and its supporters say the protests are antisemitic, a charge that Israel’s critics say is sometimes used to silence legitimate opposition. Although some protesters have been caught on camera making antisemitic remarks or violent threats, protest organizers, some of whom are Jewish, say it is a peaceful movement aimed at trying to save the lives of Palestinians civilians.

Many Democrats, from Biden on down, avoided saying much about the situation until recently as universities began to crack down and comparisons were made to anti-war protests of the 1960s.

Even then, Democrats balanced their criticism of antisemitism and rule-breakers with the need to protect the right to free expression and peaceful protest. Some have tried to avoid taking sides in protests that have pitted pro-Israeli versus pro-Palestinian Democrats and divided important parts of the party’s base, including Jewish, Arab American and younger voters.

Republicans, meanwhile, have railed at what they characterized as equivocating or silence by Democrats. Republicans professed solidarity with Jews against antisemitism while condemning the protests as lawless.

Mike Rogers, a Republican seeking an open Senate seat in Michigan, said student protesters at Columbia were “Hamas sympathizers.” In California, GOP Senate candidate Steve Garvey called them “terrorists” practicing “terrorism disguised as free speech.”

In five states, the National Republican Senatorial Committee, the Senate Republicans’ campaign arm, is using the protests in digital ads about student loan forgiveness, saying Democrats want to pay off the loans of students “radicalized by the far left” who are “threatening Jews,” “attacking police” and “acting like terrorists.”

McCormick and others say universities that, in their view, tolerate antisemitism should lose federal subsidies and that visas should be revoked for any foreign student inciting violence or expressing pro-Hamas sentiments at the encampments.

Casey, long a staunch supporter of Israel, has criticized acts of antisemitism on campuses and pointed to legislation he sponsored as a way to make sure the Education Department takes action.

“Students of course have the right to peacefully protest, but when it crosses the line either into violence or discrimination, then we have an obligation to step in and stop that conduct,” Casey said Thursday as he urged colleagues to pass his bill.

Democratic Sen. Jacky Rosen of Nevada, who is Jewish and facing reelection, said she was “horrified” by displays of antisemitism on campuses and, like Casey, called for the department to hold schools accountable.

In California, U.S. Rep Adam Schiff, the Democratic nominee for an open Senate seat, took aim at the Columbia demonstration and said “antisemitic and hateful rhetoric is being loudly and proudly displayed.” Accused by Garvey of being “incredibly silent” on the protests, Schiff, who is Jewish, voted for a House bill similar to Casey’s and released a statement that condemned violence and the “explicit, repeated targeting and intimidation of Jewish students.”

Republicans elsewhere contended statements by Democrats were equivocating and inadequate.

Republicans called out Sen. Sherrod Brown, D-Ohio, after he told an Axios reporter last week that he was “not going to talk about the politics of that. People always have the right to speak out and should.”

His Republican opponent, Bernie Moreno, charged that Brown had “wholeheartedly endorsed these vile and violent antisemitic demonstrations.”

Later, at a news conference, Brown gave more expansive comments. “Students want to make their voices heard, they need to do it in a way that’s nonviolent, they need to do it in a way that doesn’t spew hatred, and laws need to be enforced,” he said.

In Michigan, which has a relatively significant Muslim population, Biden’s handling of the war is expected to factor heavily into the presidential and Senate races.

Rogers, a favorite for the GOP nomination, thanked New York City police for confronting protesters and “standing up to protect Jewish students at Columbia from the visceral hatred we’ve witnessed from Hamas sympathizers on their campus.”

Republicans argued that U.S. Rep. Elissa Slotkin, the front-runner for the Democratic nominationfor Senate, had not spoken out strongly against protests at Columbia, her alma mater, and that she took five days after they began to say anything at all.

Slotkin, who is Jewish, said in an April 22 statement — the most recent wave of demonstrations began at Columbia on April 17 — that “the use of intimidation, antisemitic signs or slogans, or harassment, is unacceptable.”

It was, she suggested, a complicated topic.

“I would rather be thoughtful and take more time than have a knee-jerk answer for any issue,” Slotkin said in an interview. “But especially this one.”

At least 13 people died in northern Haiti following two days of heavy rains, officials said.

The majority of the deaths were caused by a landslide in the southeastern region of the coastal city of Cap-Haitien, according to a Thursday statement by Haiti’s Civil Protection Agency.

GANGS IN HAITI LAUNCH FRESH ATTACKS, DAYS AFTER A NEW PRIME MINISTER IS ANNOUNCED

More than 2,200 homes also were flooded, and there were significant losses in livestock swept away by the Haut-Cap river, authorities said.

Crews were clearing roads across northern Haiti, with additional rain expected in upcoming days.

Heavy rains also were reported in neighboring Puerto Rico, forcing at least a dozen flights scheduled to land in the capital of San Juan to reroute to the Dominican Republic and elsewhere, officials said Friday.

Widespread flooding also was reported in the U.S. territory.

The death toll has climbed to 56 in Brazil’s southern Rio Grande do Sul state, with tens of thousands displaced.

Overpowering floods and mudslides caused by torrential rains are continuing to sweep southern Brazil, killing at least 56 people and forcing tens of thousands out of their homes, the government said.

As well as raising the death toll on Saturday, the country’s civil defence agency said rising water levels in the state of Rio Grande do Sul were straining dams and threatening the metropolis of Porto Alegre.

Triggered by storms that began on Monday, the flooding is only expected to get worse, local authorities said, as rescuers scoured the ruins of washed-out homes, bridges, and roads for missing people.

“Forget everything you’ve seen, it’s going to be much worse in the metropolitan region,” Governor Eduardo Leite said on Friday as the state’s streets were submerged.

‘Nothing could be saved’

The flooding, Brazil’s worst in 80 years, has so far affected at least 265 municipalities in Rio Grande do Sul, according to the southernmost state’s civil defence department.

It has injured at least 74 people, displaced more than 24,000, and left 350,000 with some form of property damage.

“Nothing could be saved,” said Claudio Almiro, who lost his home and possessions to the flooding.

“Many people have even lost their lives. I raise my hand to heaven and thank God that I’m alive.”

Residents in several cities and towns have been left completely cut off from the world, with no electricity or telephone access, while others have been forced to abandon their livestock.

“You don’t know if the water will continue to rise or what will happen to the animals, they may soon drown,” said Raul Metzel, from Capela de Santana, north of the state’s capital.

Five days in, as the rainfall shows no signs of letting up, four of the state’s dams are at risk of collapsing, creating the risk of a new “emergency situation”, according to civil defence officials.

Brazil’s federal government has sent aircraft, boats and more than 600 soldiers to help clear roads, distribute food, water and mattresses, and set up shelters, while local volunteers have also helped with search efforts.

‘Disastrous cocktail’

Climatologist Francisco Eliseu Aquino said the devastating storms were the result of a “disastrous cocktail” of global warming and the El Nino weather phenomenon.

South America’s largest country has recently experienced a string of extreme weather events, including a cyclone in September that killed at least 31 people.

Aquino said the region’s particular geography meant it was often confronted by the effects of tropical and polar air masses colliding – but these events have “intensified due to climate change”.

And when they coincide with El Nino, a periodic warming of the waters in the tropical Pacific, the atmosphere becomes more unstable, he said.
