Sen. Joseph Lieberman will make a statement on Wednesday about whether he will run for re-election in 2012.
He will announce his decision in Stamford at 12:30 p.m.
The announcement came in an e-mail from one of Lieberman's press office staff members.
Aides tell NBC News "After many thoughtful conversations with family and friends over the last several months, Senator Lieberman made a decision about his future over the holidays which he plans to announce on Wednesday."
Lieberman, a long-time Democrat, was elected as an Independent in 2006 after losing the Democratic primary to Ned Lamont.
Since then, he has often sided with Republicans in the Senate, and there has been a lot of talk about whether Lieberman's next run would be as an Independent, Democrat or as a Republican.
In December, Lieberman told Andrea Mitchell, of NBC, that he still had some decisions to make.
"I've got a couple of decisions to make, and they're important ones to me and my family. The first one is, do I want to run again? I really love being a Senator. I feel good about what I've done, but every time you come to it, I think you've got to decide if you really want to do it for six more years," he said.
She also asked him about which party he'd run with.
"If I run again, it's more likely that I'll run as an Independent. But we'll see. We've got a lot of talking and thinking to do over the break with family and friends, and I hope to announce sometime early next year," he said.
That announcement comes on Wednesday.
