The White House is still refusing to comment on Jimmy Hoffa’s profane, threatening warm-up speech before President Obama’s Labor Day gig in Detroit yesterday.

They’ve got each other’s back.

Here’s a flashback from May 2008 that you may remember.

Sen. Barack Obama won the endorsement of the Teamsters earlier this year after privately telling the union he supported ending the strict federal oversight imposed to root out corruption, according to officials from the union and the Obama campaign. …John Coli, vice president for the Teamsters central region, who brokered the Teamsters endorsement, said Sen. Obama was “pretty definitive that the time had come to start the beginning of the end” of the three-member independent review board that investigates suspect activity in the union. Mr. Coli said that Sen. Obama conveyed that view in a series of phone conversations and meetings with Teamsters officials last year. …Obama spokesman Tommy Vietor confirmed the candidate’s position in a statement to The Wall Street Journal, saying that Sen. Obama believes that the board “has run its course,” because “organized crime influence in the union has drastically declined.” Mr. Vietor said Sen. Obama took that position last year.

Son of a…never mind.
