A day after disgraced former coal executive Don Blankenship showed up at a protest outside a Hillary Clinton campaign event in West Virginia, the campaign struck back by saying it was “proud” not to have his support.

Talley Sergent, the state director in West Virginia for Clinton’s campaign, said Blankenship’s presence outside a campaign stop was “pretty outrageous.” Blankenship, the former CEO of Massey Energy, was in charge of a mine that blew up and killed 29 people in 2010 in West Virginia. He was sentenced last month to a year in jail for conspiring to violate federal mine safety standards.
