US President Donald Trump told reporters Thursday that he will leave the White House if the Electoral College votes for Democrat Joe Biden, TASS reported.

The respective video was broadcast by all main US TV channels.

"If they do [vote for Biden – TASS], they made a mistake," Trump said.

When asked, whether he would leave the White House under that outcome, Trump said, "Certainly I will."

"It's going to be a very hard thing to concede because we know there was massive fraud," Trump added.

The inauguration of the next US President is due to be held on January 20.
