After nearly two weeks of cross-country jousting, Gov. Gavin Newsom of California waited alone Friday at the bottom of the steps outside Air Force One to greet President Trump as he arrived in Los Angeles to tour wildfire damage.

It wasn’t clear how the meeting would go. Mr. Trump often derides the governor as “Newscum.” And Mr. Newsom has accused Mr. Trump of orchestrating an assault on the 14th Amendment by signing an executive order to end birthright citizenship.

But after Mr. Trump exited the plane and walked slowly down the steps, the two men greeted each other with a long warm handshake and shoulder clasps. Mr. Trump then brought Mr. Newsom with him to speak to waiting reporters.

“I appreciate the governor coming out and meeting me,” Mr. Trump said, wearing a dark blazer and a “Make America Great Again” baseball hat. “Very much.”

Mr. Newsom, dressed in bluejeans and a denim, button down shirt, echoed the sentiment. “Thank you for being here. It means a great deal.”

It is hard to imagine two officials who are more ideologically different. If Mr. Trump is the leader of conservative America,phl63 gaming Mr. Newsom is one of the most prominent leaders of liberal America. They both relish their respective roles.

Ms. Harris may give remarks about border issues during the visit, according to the people, who insisted on anonymity to discuss a trip that has not yet been made public.

“What he said or didn’t say is between him and the people of North Carolina7xm,” said Mr. Vance, former President Donald J. Trump’s running mate. He added: “I’ve seen some of the statements. I haven’t seen them all. Some of them are pretty gross, to put it mildly. Mark Robinson says that those statements are false, that he didn’t actually speak them. So I think it’s up to Mark Robinson to make his case to the people of North Carolina that those weren’t his statements.”
