The Donald Trump camp claims that campaign manager Corey Lewandowski was not the one who yanked a protester by his shirt collar in a video from Trump’s Saturday rally in Tucson, Ariz.

In a statement, the Trump campaign says it was the man to Lewandowski’s left who reached out to pull the protester back. The protester can be seen shoving the second man, and the campaign argues that he was reacting to whoever pulled him.
