The US Secret Service postponed a meeting where it was due to field questions from Congress about why agents failed to prevent a gunman from almost killing Donald Trump, as the agency increases protection for the former president.
Secret Service Director Kimberly Cheatle had been due to brief the House Homeland Security Committee in virtual meeting but asked for the session to be rescheduled, according to a panel aide.
The aide said the committee expects to receive an alternative briefing date from Secret Service promptly.
The Secret Service was also due to brief members of the House Oversight Committee tomorrow, and Cheatle was expected to appear before that panel for a full-scale hearing on 22 July.
The assassination attempt has raised serious concerns in Congress about how the alleged shooter was able to access a nearby rooftop with a direct line of sight to where Mr Trump was speaking.
Mr Trump will receive his party's official 2024 nomination for president during the four-day Republican National Convention in Milwaukee, which begins today.
US President Joe Biden said yesterday he had ordered an independent review, and Republican lawmakers vowed swift investigations.
In her first major statement since the shooting, which killed a rally attendee, Ms Cheatle said the agency was increasing security for Mr Trump and the Republican convention.
"I am confident in the security plan our Secret Service RNC coordinator and our partners have put in place, which we have reviewed and strengthened in the wake of Saturday's shooting," Ms Cheatle said in a statement.
Mr Trump said a bullet grazed his ear during the Saturday rally but that he is doing fine. He travelled to Milwaukee yesterday.
