Harris and Trump meet for the first time, and shake hands

As Vice President Kamala Harris and former President Donald Trump took the stage Tuesday night for their first presidential debate against each other, the two shook hands -- the first time two presidential candidates have shaken hands since 2016.

The debate marks the first time the two candidates have met each other, with Harris initiating the handshake.

After they were introduced, Trump appeared to head to his podium without shaking Harris' hand. Harris was heading to the middle of the stage, and changed course to meet him at his podium for a handshake.

The vice president said, "Kamala Harris. How are you?"

"Nice to see you, I'm fine," Trump said as he shook her hand.

Harris replied saying, "Let's have a good debate."

The handshake between the two candidates ended an eight-year streak of no handshakes on the presidential debate stage.

There are no rules or stipulations requiring a handshake before or after the debate.
