Secret Service agent reportedly willing to testify Trump did not lunge at him

Row comes after ex-White House aide's explosive testimony that portrayed a violent and unhinged Trump on day of Capitol attack

Senior Secret Service agents are reportedly prepared to testify that Donald Trump did not lunge for the wheel of his vehicle or physically attack the chief of his security detail after his speech near the White House on January 6 - as a former aide said he did in sworn testimony on Tuesday.

The row follows the explosive testimony to the House January 6 committee, which painted an unhinged and violent portrait of Trump on the day of the Capitol attack, in a shocking hearing many have seen as potentially loosening the former president's grip on the Republican party.
