Rep. Troy Nehls, R-Texas, said the leadership of the U.S. Capitol — not President Donald Trump — is to blame for the events of the Jan. 6 insurrection.

The congressman directed his remarks to Capitol Police officers and other members of law enforcement who attended Thursday’s hearing on former special counsel Jack Smith’s investigations into Trump’s mishandling of classified documents and his role in the January 6 attack.

“I can tell you, gentlemen, that the fault does not lie with Donald Trump,” he said, adding that the fault lies with the commanding officers.

The congressman’s comments sparked a response from at least one of the officers, who can be heard saying: “Go fuck yourself.”

The verbal dispute prompted Rep. Jim Jordan, Republican of Ohio, chairman of the House Judiciary Committee, to allow the congressman to continue his remarks.

“The point is, you weren’t prepared to deal with that today,” Nils shouted. “It was their fault, people. It was their fault.”

The hearing is an opportunity for the prosecutor to provide his inside view on the investigations, which have led to unprecedented indictments. They were thwarted once it became clear that Trump would return to the Oval Office; Justice Department policy prohibits the prosecution of a sitting president.

Republicans and the president accused Smith of pursuing a politically motivated case against the president. Trump denied any wrongdoing while attacking Smith, calling him a “criminal” who should be investigated and “put in prison.”

Smith defended his investigations in an hours-long closed-door meeting with lawmakers in December, saying he said he had “proof beyond a reasonable doubt” of what his investigations revealed. He denied accusations of bias.
