Donald Trump has some really bad — even disgusting — things to say about Kamala Harris, whom he had never met until their epic debate on Tuesday night, during which she forced him to shake her hand before causing his implosion on stage.

But their new relationship apparently blossomed overnight. And on Wednesday, they shook hands for the second time, about 12 hours after their first, at a ceremony in Manhattan commemorating the 9/11 terrorist attacks in 2001. And the pleasantries didn’t stop there.

“Good job,” Trump told Harris as they shook hands as they both arrived to sit in the front row for the memorial, a source at the event said.

Trump was seen repeating a compliment — either “good job” or something else, it was hard to tell — as their handshake lingered and the former president brought his left hand to her right between his palms. He tapped her hand twice with his left before letting go.

Former New York City Mayor and former presidential candidate Michael Bloomberg appeared to play the matchmaker. Harris was busy chatting with New York Sen. Chuck Schumer, the Senate majority leader, when Bloomberg tapped her on the arm. She turned and there stood Trump, in his trademark red tie and boxy suit.

As the two shook hands for the second time, Harris said something unintelligible to Trump and nodded during their roughly five-second conversation, after which they returned to line for the somber memorial service.

President Joe Biden stood quietly and watched it all unfold. Bloomberg stood next to Trump, who stood next to his running mate J.D. Vance.

The 9/11 anniversary was a striking contrast to the night before, when Trump spread lies about Harris’s record, suggesting again that she wasn’t really black and that it was her fault that immigrants were doing unspeakable things — all made up by right-wing conspiracy theorists — to people’s pets in a small Ohio town.

Here was Trump, railing against his political foes in a vitriolic and uniquely nasty way from the hidden comfort of social media, and behaving with graciousness and dignity toward Harris. It was unusual, but fitting, that both candidates put aside their political differences after their fiery and angry debate Tuesday night, in which Trump used far-right conspiracy theories to lead him into what pundits in both parties called a colossal failure for the former president.

Trump, 78, was also booed at the Ground Zero event, criticized for winking and smiling at photographers and looking up at the sky as other political leaders bowed their heads in remembrance of the 2,977 innocent lives lost on Sept. 11, including 2,603 ​​at the World Trade Center.
