A shouting match between Rep. Pat Fallon and Secret Service acting Director Ronald Rowe broke out during the final hearing of the House task force investigating the two assassination attempts on President-elect Donald Trump.

Mr. Fallon, Texas Republican, accused Mr. Rowe of attending a 9/11 remembrance event for political visibility, igniting a loud, chaotic back and forth between the two men.

Mr. Fallon was the second to last member of the task force to question Mr. Rowe at the hearing.

The exchange went off the rails when Mr. Fallon brought out a poster board with a photo of a 9/11 remembrance event with Mr. Rowe pictured standing near President Biden and Vice President Kamala Harris. Mr. Trump and Vice President-elect J.D. Vance were also pictured at the remembrance event on September 11 of this year.

He asked Mr. Rowe who is usually closest to the president, security-wise. Mr. Rowe said that it is typically the special agent in charge of the presidential detail, to which Mr. Fallon asked if that was Mr. Rowe’s position.

Mr. Rowe said the special agent in charge was just out of the frame of the picture and started to preemptively defend himself from where Mr. Fallon was going with the questioning.

“That is the day where we remember the more than 3,000 people that died on 9/11. I actually responded to ground zero. I was there going through the ashes at the World Trade Center.”

Mr. Fallon started yelling that it was not what he was asking, and the two engaged in a shouting match with a lot of cross-talk, as Mr. Fallon accused Mr. Rowe of trying to use the 9/11 event “for political purposes.”

“I’m not,” Mr. Rowe said as both men shouted over each other.

“You know why you were there because you want to be visible,” Mr. Fallon said.

Mr. Rowe told him he was “out of line.”

Throughout the intense argument, Rep. Mike Kelly, the task force’s chairman, banged his gavel trying to regain control of the hearing. The shouting finally ended after more than a minute, and the hearing concluded without further controversy.

The outbursts appeared to frustrate other panel members who have repeatedly touted the panel’s bipartisanship, its focus on the facts of the assassination attempts and its recommendations for improvement.

Rep. Kelly, Pennsylvania Republican, spent time immediately after the exchange whispering with Rep. Jason Crow of Colorado, the task force’s top Democrat. Later, Mr. Fallon came over to join in the conversation.

It was not clear what they said to one another, but Mr. Kelly and Mr. Crow both used their closing remarks to praise Mr. Rowe for his cooperation and efforts to remediate issues at the Secret Service in the wake of the assassination attempt.

Without directly addressing Mr. Fallon’s questioning of Mr. Rowe, they both said the hearing and the investigation adhered to their goal of a bipartisan fact-finding mission.

“You couldn’t watch this hearing today and see who is a Democrat and Republican,” Mr. Crow said, suggesting the public watch the entirety of the hearing.
