Former President Donald Trump on Friday night blamed the stage contractor after appearing to momentarily wobble during his rally in St. Paul, Minnesota.

A clip of the moment was posted by the X, formerly Twitter, account Biden-Harris HQ, which is associated with President Joe Biden’s reelection campaign. In the footage, Trump leans on his podium and tips toward the left while addressing his supporters, moving the dais with him.

“You know, this is the worst platform,” Trump said after his lurch. “Who put this stage up?”

“It keeps tilting further left,” the former president added. “Like too many other things.”What a crappy contractor this was.”
