Filmmaker Michael Moore took to Twitter Sunday afternoon to share his opinion with followers that combat snipers are “cowards.”

Moore’s words came amid a record-breaking box office weekend for Clint Eastwood’s American Sniper, which made its wide U.S. theatrical debut Jan. 16.

He tweeted:

The Fahrenheit 9/11 director likely made the comment in reference to Bradley Cooper’s portrayal of Navy SEAL Chris Kyle in the Eastwood-directed film, which has celebrated a $100 million weekend since its nationwide release Friday, and has been nominated for six Academy Awards.

Moore also tweeted Friday to remind followers to watch Selma, and thanked President Barack Obama for holding an official White House screening of the film Friday night.
