John McCain’s colleagues are remembering him in speeches on the floor of the Senate, where he served for more than 30 years.

Republican Sen. Orrin Hatch of Utah says McCain reached “the pinnacle of American” life as a “happy warrior.”

Democratic Sen. Chris Coons of Delaware remembers him as “a treasure and a challenge” for his patriotism and trademark brusqueness.

McCain’s best friend in the Senate, South Carolina Republican Lindsey Graham, is set to eulogize the Arizona Republican later Tuesday.

Senate leaders are considering ideas to honor McCain on Capitol Hill, including renaming the Russell Senate Office Building for him, although Senate Majority Leader Mitch McConnell appeared to hit the brakes on that idea Tuesday, saying he would form a bipartisan panel to determine a tribute.

McCain died Saturday at 81 from brain cancer.
