Democratic West Virginia Senator Joe Manchin says that he has been friends with the Clinton family for “a long time” — but what Hillary said about coal miners during the 2016 election was “horrific.”

Watch the clip above to see Sen. Manchin explain why he believes it was “just horrible, what she said.”
