Sky News host James Morrow has called for US President Joe Biden to demand the resignation of Secret Service Director Kimberly Cheatle.

This comes as the Secret Service is under scrutiny amid revelations of possible security failures during Donald Trump’s Pennsylvania rally, where a shooter attempted to assassinate the former US president.

“If anyone from the Biden White House is watching this ... let me give a few recommendations for the President,” Mr Morrow said.

“One, he should demand the resignation of Kimberly Cheatle, the head of the Secret Service, to make it absolutely clear there are consequences for this gross incompetence.

“There is zero downside and a lot of political upside if he really wants to reach out across the aisle.”
