Republican National Committee (RNC) Chairwoman Ronna Romney McDaniel warned Wednesday that those who don't embrace President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?' Romney: 'Unthinkable and unacceptable' to not commit to peaceful transition of power Two Louisville police officers shot amid Breonna Taylor grand jury protests MORE's agenda "will be making a mistake."

McDaniel sent the stern message on Wednesday night, and was met with backlash from conservatives, liberals and members of the media.

She later sought to clarify her message in a second tweet, noting it reflected comments she made to Lou Dobbs on Fox News Business.

"Complacency is our enemy. Anyone that does not embrace the @realDonaldTrump agenda of making America great again will be making a mistake," McDaniel said in the initial tweet on Wednesday night.

Social media users quickly pointed out what appeared to be a threatening tone in McDaniel's tweet.

"What in the actual hell.... is this a threat Ronna?" tweeted Meghan McCain, co-host of ABC's "The View" and daughter of Sen.

McDaniel added context for her answer in a subsequent tweet on Thursday morning, saying it "didn't translate well" with Twitter's character limit.

She posted a photo of her full comments to Dobbs, where she argued that Republicans should continue pushing Trump's agenda ahead of the November midterm elections.

"Mark Sanford has been very unhelpful to me in my campaign to MAGA (make American great again). He is MIA and nothing but trouble. He is better off in Argentina," Trump tweeted Tuesday afternoon, referencing the congressman's 2009 affair.

"I fully endorse Katie Arrington for Congress in SC, a state I love. She is tough on crime and will continue our fight to lower taxes. VOTE Katie!" he wrote.
