The nonprofit’s super pac supports the Problem Solvers Caucus, which has 44 equally divided Democratic and Republican members in the House and purports to be working on real solutions to issues that divide Congress.

But over the past year, No Labels’ leaders considered primary challenges to at least three incumbent House Democrats—starting with Pelosi, in January 2017. They also discussed running a primary challenge to freshman Darren Soto, a Florida Democrat. He had been elected with No Labels’ support but had in early 2017 accepted a mostly honorific position as an assistant whip for the House Democrats.

Now Soto is one of the nine Democrats from the Problem Solvers Caucus who is among the holdouts in Pelosi’s bid to win another term as speaker. Those nine currently have considerable influence as she works to reach the number of votes she needs to be elected speaker. Soto and his fellow Democrats in the caucus announced last week that they would not support Pelosi unless she agreed to rule changes that they argue would “break the gridlock.” Pelosi is scheduled to meet with its members on Tuesday, though she preempted the conversation by having an aide put out a statement arguing that she’s already agreed to many of their proposals and gone further.
