Biden says he believes Putin will go through with Ukraine invasion within days

He spoke as he was leaving the White House on a trip to Ohio.

President Joe Biden on Thursday said he believes Russian President Vladimir Putin will go through with an invasion of Ukraine within days.

"My sense is this will happen in the next several days," he told ABC News Chief White House Correspondent Cecilia Vega as he left the White House for a trip to Ohio.

Biden told reporters the threat of an invasion is "very high."

"They have not moved any of their troops out. They have moved more troops in," he said. "We have reason to believe that they are engaged in a false flag operation, to have an excuse to go in. Every indication we have is they're prepared to go into Ukraine and attack Ukraine."
