"He's unstoppable" Pence says in apparent reference to Trump

U.S. Vice President Mike Pence has made an apparent reference to President Donald Trump's impeachment troubles, saying the Republican leader was "unstoppable" in a conversation with Israel's prime minister caught on camera.

"We're contending.

He's unstoppable.

Like somebody else I know," Pence told Benjamin Netanyahu on Thursday (January 23), after the prime minister greeted him and asked a question, which was inaudible, at a Holocaust memorial event in Jerusalem.

An impeachment trial is under way in the U.S. Senate, with Democrats accusing Trump of a corrupt scheme to pressure Ukraine to help him get re-elected.

Indicted on corruption charges, Netanyahu - who has asked for parliamentary protection from prosecution - could also face his own trial.

Both leaders deny any wrongdoing.
