(The Hill) — AFL-CIO President Richard Trumka implored liberal activists Thursday to get behind President Obama’s jobs bill.

Speaking at the Take Back the American Dream conference, the head of the nation’s largest labor federation said activists should support the White House’s $447 billion proposal, which includes funding to repair infrastructure, modernize school buildings and provide aid to local and state governments. Trumka said the legislation would help build a nationwide movement on jobs.

“Our first step is to support President Obama’s American Jobs Act and his demand that the millionaires and billionaires who have profited so handsomely pay their fair share of taxes to create jobs,” Trumka said.

The labor leader said that in the past, he has not held back from criticizing the president when he felt Obama was heading down the wrong path.

“See, like many of you in this room, I’ve been one of the first to call out President Obama when I thought it was needed. But when he’s doing the right thing, when he’s doing the courageous thing, it’s time for us to have his back and push that bill through,” Trumka said to applause.

Trumka’s support comes at a crucial time in Obama’s presidency. Obama will need the help of unions to persuade working-class voters he deserves a second term, and labor’s extensive get-out-the-vote operations could be a difference-maker in battleground states.
