U.S. Sen. Elizabeth Warren said she will vote to repeal the state’s casino law when the hotly debated question goes to the ballot in November.

“I come to the question of gambling from a background in bankruptcy and what happens economically to families,” the Cambridge Democrat told reporters yesterday. “It’s a tough call here. People need jobs, but gambling can be a real problem economically for a lot of people. I didn’t support gambling the first time around and I don’t expect to support it (now).”

Warren’s comments came after she delivered a fiery speech at the Greater Boston Labor Council’s annual Labor Day breakfast, where she’s spoken the past four years, often bathing in adulation from the organized labor crowd that helped propel her into the Senate.

Her stance, however, comes in direct conflict with that of the AFL-CIO, the state’s largest labor organization, which hung a banner over the stage yesterday declaring “no” on Question 3, which would repeal the casino law.

“It’s about jobs,” the banner read.

Warren, speaking to reporters, did not speculate on whether the casino law repeal question would pass.

“We’ve had this vote before, and now we’ll have the chance to take a second look,” she said. “We’ll have a little more information than we had before and I’m not sure how it will turn out. This is why people have the chance to get out and vote on it.”
