A shouting match broke out at a hearing to investigate the assassination attempts on President-elect Donald Trump's life during his presidential campaign.
Republican Congressman Pat Fallon accused Secret Service Director Ronald Rowe of "playing politics" and endangering President Joe Biden's life when attending a 9/11 memorial with Trump and Vice-President Kamala Harris because he wasn't there in a security capacity.
Rowe, who replaced previous Director Kimberly Cheatle after she resigned in July following the first assassination attempt in Butler, Pennsylvania, told Fallon he was "out of line" and that he had been there to honour the lives of the Secret Service members that died on 9/11.
