Schumer-aligned group that meddled in GOP primary hit with complaint alleging FEC violations

FIRST ON FOX: A group aligned with Senate Majority Leader Chuck Schumer, D-N.Y., has been hit with a complaint alleging they have violated Federal Election Commission (FEC) rules. 

The mysterious entity, called the Last Best Place PAC, recently jumped into the Montana Senate race and began spending millions to target former Navy SEAL Tim Sheehy ahead of the state's Republican primary. 

The Last Best Place PAC is financially driven by Majority Forward, a dark money nonprofit that has put hundreds of thousands toward the Schumer-aligned Senate Majority PAC for salaries, insurance and IT security. Federal records filed last week show Majority Forward funneled $2.14 million to the Last Best Place PAC and was its only funder.
