OTTAWA - Firebrand New Democrat MP Pat Martin is at it again on Twitter.
Martin is making headlines for an abusive series of tweets prompted, apparently, by the Conservative government's failure to invite him to an announcement in his Winnipeg Centre riding.
The tweets include some particularly scathing and personal insults aimed at Public Safety Minister Vic Toews and the Conservative party.
Martin describes the Conservatives as "truly bad people" who won last year's federal election using "American-style dirty tricks."
It's not the first time Martin has used his access to the social-networking service to raise eyebrows.
In November 2011, Martin went on a similar tirade when the government used procedural tools to shut down debate on a budget bill.
