Ruggerio, 76, a North Providence Democrat, missed long stretches of last year’s legislative session as he battled cancer and shingles. He is still being treated for cancer, he said on Tuesday.

In November, Ruggerio withstood a leadership challenge from former Senate Majority Leader Ryan W. Pearson, a Cumberland Democrat who charged that the Senate was ineffective in his absence.

Ruggerio was admitted to Our Lady of Fatima Hospital, in North Providence, on Feb. 19 with what senators were told was a “touch of pneumonia.” He later moved to Fatima’s rehabilitation facility, and returned home on March 12. He was expected to return to the Senate last Thursday, but a spokesman said he needed another day with his recovery.

With his appearance Tuesday, Ruggerio has attended six the Senate’s 13 sessions this year. He presided over Tuesday’s Senate session, which included unanimous approval of two bills.

During announcements Tuesday, Senator Jake Bissaillon, a Providence Democrat who previously served as his chief of staff, said to Ruggerio, “I’d be remiss not to say it’s good to see you back.”

After Tuesday’s session, Pearson said, “I’m glad to see he is doing well enough to be back.”

When asked by reporters what his priorities are for the remainder of the legislative session, Ruggerio said, “Well, I’m playing catch up.”

But he cited a Senate commission appointed to study whether to create a medical school at the University of Rhode Island. And he mentioned the package of health care bills that the Senate unveiled in February, including legislation to review Medicaid reimbursement rates for primary care providers in Rhode Island.

Ruggerio said he has not had a chance to meet with Governor Daniel J. McKee or House Speaker K. Joseph Shekarchi to discuss legislative priorities. “We’ve spoken over the phone. I haven’t really met with them physically, but I intend to,” he said.

When asked to identify the hardest part of being Senate president during his health problems, Ruggerio said, “Keeping up with things.” He emphasized his “great staff,” and said he is in regular contact with Senate staff, Shekarchi, and McKee. “So I can keep up with what’s going on up here,” he said.

Ruggerio is considered the “dean” of the Senate, the chamber’s longest-serving member, first winning election in 1985. He previously served in the state House of Representatives from 1981 to 1984, and has served as Senate president since March 2017.

When the 2025 legislative session commenced in January, the 38-member Senate reelected Ruggerio as president, with 26 senators voting for him while 12 voted “present,” essentially abstaining from the vote. Surprisingly, Ruggerio was among those who voted “present.” Afterward, he said he could not hear and misunderstood when he voted “present” rather than voting for himself.

When asked on Tuesday if he still considers it a good decision to run again for Senate president, Ruggerio said, “Yes.”
