Washington (CNN) A conservative strategist and defender of Supreme Court nominee Brett Kavanaugh apologized Friday for making "an appalling and inexcusable mistake" when he claimed Thursday that Kavanaugh's accuser had misidentified her alleged assailant as Kavanaugh.

In a tweet, Ed Whelan, the president of the Ethics and Public Policy Center and, according to The Washington Post, a strategist helping Kavanaugh navigate claims of sexual assault by Christine Blasey Ford, said he "takes full responsibility for that mistake, and I deeply apologize for it."

I made an appalling and inexcusable mistake of judgment in posting the tweet thread in a way that identified Kavanaugh's Georgetown Prep classmate. I take full responsibility for that mistake, and I deeply apologize for it. I realize that does not undo the mistake. — Ed Whelan (@EdWhelanEPPC) September 21, 2018

In a series of tweets that have since been deleted, Whelan said Ford may have confused Kavanaugh for a different classmate, one that he named in the tweets along with the address of the house where he suggested the reported attack had taken place.

According to the paper, Ford denied she had confused the man Whelan named for Kavanaugh, who she alleges attacked her at a party in the 1980s when they were students at Washington-area schools. Kavanaugh has denied Ford's allegations.
