Three days after creating a social media firestorm by calling a reporter a bitch on Twitter, Senator Patrick Brazeau appears to have deleted his account.

The Twitter handle he used, @TheBrazman, no longer exists.

He apologized Tuesday for telling Canadian Press parliamentary journalist Jennifer Ditchburn to change her last name to “Bitchburn” after she reported that Brazeau, Canada’s youngest senator, had the lowest attendance record in the Red Chamber between June 2011 and April 2012.

Ditchburn looked at records in the Senate attendance register, and noted that Brazeau was absent for 25 per cent of the 72 sittings during that period. Brazeau also missed 65 per cent of meetings of the aboriginal peoples committee on which he sits and did not attend 31 per cent of the meetings of the human rights committee, on which he serves as deputy chair, Ditchburn reported.

Shortly after Ditchburn’s story was posted online, a message appeared on Brazeau’s Twitter account, saying: “@jenditchburn while u smile Jen, others suffer. Change the D to a B in your last name and we’re even! Don’t mean it but needs saying.”

Ditchburn replied: “Dear Senator: Many a person has made fun of my name and (t)he word “Bitch.” But never a Canadian senator. That’s a first.”

Dozens of Twitter users immediately lashed out at Brazeau, calling his comment unprofessional and sexist. Many questioned his appointment to the Senate and called for his resignation.

Brazeau eventually tweeted an apology and also phoned Ditchburn the next day to apologize to her directly.

On Wednesday, Brazeau got into another Twitter spat, this time with an APTN journalist who wrote a story about allegations of sexual harassment against the Senator, which have not been proven in court.

Friday afternoon, Liberal MP Justin Trudeau, who beat Brazeau in a charity boxing match this spring, tweeted: “Pat, I say this against my own self-interest, but for God’s sake stop tweeting. PMO goons hit even harder than I do.”

It’s unclear whether @TheBrazman Twitter account was deleted before or after Trudeau’s tweet was posted.
