Senator Patrick Brazeau threw an Olympic jab at Liberal MP Justin Trudeau on Twitter, less than a month after reactivating his account.

Brazeau, who was defeated by Trudeau in a charity boxing match on Parliament Hill in March, wrote, "Perhaps it's just me but why hasn't @justinpjtrudeau congratulated any of our Canadian athletes? Is it because of his separatist comments?"

Soon after, Brazeau took to attacking the Liberal Party of Canada's position on First Nations, to shift the narrative away from his critique of Trudeau's social media presence, and Québécois heritage.

"If I say "Go Canada Go", are leftistsgoing [sic] to take it out of context because not only am I Canadian 1st but because I'm also a 1st Canadian?" wrote Brazeau, on Friday.

Responding to another user, he wrote, "name one thing the LPC did for FN people in the last 10 yrs? I look forward to that response regardless of your stripes."

As a result, several people fired back at Brazeau, calling him "petty," "jealous," and writing, he should "grow up." Another user, @YasminSadeghi, wrote, "didnt Harper specifically ask you not to tweet insulting things? I remember he told you after you made sexist comments."

Even the National Post's Steve Murray was taken aback by the senator's comments against Trudeau, and remarked, "As a politician do I have to congratulate each Canadian Olympic athlete on twitter? Or can I just do a blanket, "Congrats to all!" thing?"

No stranger to controversy, Brazeau took a two-week Twitter hiatus on June 29 after insulting Jennifer Ditchburn, a journalist. "The Brazman" called Ditchburn a "bitch" when she wrote about his poor attendance record in the senate.

"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," the senator tweeted from his account, on June 26.

He later apologized over the phone, which the CP reporter accepted.

Upon making his social media return in mid-July, CTV News reports that Brazeau promised to "be nice from now on," but it appears the senator has strayed from his own advice.

The 37-year-old is the youngest sitting senator in Canada, and was absent for 25 per cent of the 72 sittings between June 2011 and April 2012, giving him the poorest attendance record in that parliamentary session. In 2009, Brazeau became an appointed senator, and was National Chief of the Congress of Aboriginal Peoples.
