The lead guitarist of a popular band apologized and announced Wednesday he is “taking time away from the band” after he praised Andy Ngo’s book about antifa’s “radical” history and tactics.

Winston Marshall, member of Mumford & Sons, announced on Twitter that he was “truly sorry” for offending so many people after he praised Ngo’s book “Unmasked: Inside Antifa’s Radical Plan To Destroy Democracy.” In a tweet Marshall reportedly deleted Sunday night, he congratulated Ngo, who covered riots in Portland, Oregon, and has claimed he received “hundreds of threats” from Antifa.

“Congratulations @MrAndyNgo,” Marshall said in his tweet. “Finally had the time to read your important book. You’re a brave man.”

Soon after the tweet, Twitter users decried Marshall and Mumford & Sons as fascists.

The weak, pussified, moron released this statement:

Over the past few days I have come to better understand the pain caused by the book I endorsed. I have offended not only a lot of people I don’t know, but also those closest to me, including my bandmates and for that I am truly sorry. As a result of my actions I am taking time away from the band to examine my blind spots. For now, please know that I realize how my endorsements have the potential to be viewed as approvals of hateful, divisive behaviour. I apologize, as this was not at all my intention.
