A reporter at The Republican resigned Friday after publishing a Twitter post that falsely indicated the suspect who is charged with killing five people at an Annapolis Maryland newspaper was wearing a President Trump-inspired "Make America Great Again" hat.

Conor Berry took full responsibility for the unauthorized tweet. "I am ashamed of my tweet, which taints the good work of fair-minded journalists everywhere," Berry wrote in his resignation notice.

"We need to be more vigilant than ever to be fair and accurate in a climate in which we are scrutinized and criticized," Wayne Phaneuf, executive editor of The Republican, said. "The Republican newspaper and our partners at MassLive.com are committed to report the news with the truth paramount."

Phaneuf added that when an editor at The Republican became aware of the Twitter post, it was quickly taken down.
