Sen. Rick Scott (R-Fla.), one of the wealthiest members of the Senate, has joined music star Kid Rock and fight promoter Dana White in donating $50,000 to the GoFundMe campaign set up to the victims of the shooting at Donald Trump’s rally in Butler, Pennsylvania.

“I donate my Senate salary every quarter and am honored to join @KidRock, @danawhite, @ufc and others in supporting the victims of the Butler shooting. I am sending $50K to this great cause,” Scott posted on the social media site X.

The fundraising effort had raised more than $2.3 million by Sunday and will go to the victims and grieving family of Corey Comperatore, who was killed in the shooting. Comperatore, a volunteer fire chief, used his body to shield family members.

Two other victims were listed in stable condition after the shooting.

Kid Rock shared a link to the GoFundMe page with supporters through his social media site along with a video supporting Trump.

Former GOP presidential candidate Vivek Ramaswamy donated $30,000 to the cause.

Scott has also demanded the Senate Homeland Security Committee hold a hearing this month to call in officials from the Department of Homeland Security and Secret Service to explain how the shooter got so close to the president.

“The assassination attempt on President Trump and murder of an innocent American demands immediate answers,” Scott said in a statement. “It is a miracle that President Trump is alive and well but absolutely inexcusable that the deranged would-be assassin had a direct line of sight to the former president and the leading candidate for president of the United States.”

Scott is a member of the Homeland Security Committee, which is chaired by Sen. Gary Peters (D-Mich.).

Sen. Ron Johnson (R-Wis.), another senior Republican on the panel, has called for a congressional investigation into the shooting.

“It was a failure,” Johnson told CNN’s “State of the Union” on Sunday. “There absolutely have to be congressional oversight hearings.”
