Kamala Harris and Donald Trump shake hands again at 9/11 memorial ceremony

Vice President Kamala Harris and former President Donald Trump shook hands again Wednesday morning as they arrived at the 9/11 memorial ceremony in downtown Manhattan.

Harris, standing between New York Sen. Chuck Schumer and President Joe Biden, reached across the president to shake hands with Trump, who was standing next to former New York City Mayor Michael Bloomberg, after Harris appeared to be egged on by Bloomberg.

Trump described the exchange as “very civil” when asked about it later in the day during his visit to the Shanksville Volunteer Fire Department in Shanksville, Pennsylvania. He did not reveal what the two candidates said to each other.

Vice presidential nominee Sen. J.D. Vance, who was standing next to Trump at the time, told Fox News the handshake was “warm and polite.”

The greeting came less than 12 hours after Harris and Trump first met during a presidential debate in Philadelphia hosted by ABC News.

The handshake between Harris and Trump on Tuesday night ended an eight-year streak of no handshakes on the presidential debate stage. There are no rules or regulations requiring a handshake before or after the debate.

After the ceremony at Ground Zero, Biden and Harris attended 9/11 commemorations in Shanksville and the Pentagon.

“On this day 23 years ago, terrorists thought they could break our will and bring us to our knees. They were wrong. They always will be wrong,” Biden said in a statement. “In our darkest hours, we found light. And in the face of fear, we came together — to defend our country and to help each other.”

“Today, our longest war is finally over. But our commitment to preventing another attack on our people will never be,” he said.
