... and when asked, Frederick Douglass did not deny her report.

She's Tweeting about something recently reported about his staffer. Then the part of the Tweet about McCain not answering questions is the title of an old article she wrote that she wants people to read to form some kind of imagined connection, conspiracy or something.

Still funny lol.

Idiot still hasn't deleted the tweet.

"Obama's Iraq invasion" was a disaster.

Mostly False

What's True

On 20 December 2018, four months after Sen. John McCain's death, Katrina Pierson did publish a tweet which contained the words "John McCain Still Refuses to Answer Questions About His Role in the Dossier."

What's False

Those words came from the headline of a November 2017 article which Pierson was sharing and automatically appeared in her tweet when she used a Twitter sharing button on the article's web page. The phrase was not the result of Pierson's ignorance about McCain's August 2018 death or any belief in the supernatural.
