U.S. Senate candidate Seth Moulton is being accused of hitting a phone out of a person's hand. 

The Boston Herald reports the person was asking Moulton whether he endorses Maine Senate candidate Graham Platner after a campaign event on Wednesday.  Moulton's campaign says the person was with America Rising, a Republican political action committee. 

The Massachusetts congressman then posted to social media later, saying he would not apologize for confronting what he called "MAGA." 

While Moulton has not officially offered an endorsement of Platner, he has publicly expressed support for his platform.
