Former New York Mayor Michael Bloomberg gave $500,000 to super PACs supporting Sens. Lindsey Graham and Thad Cochran for primary races against conservative opponents, Politico reported
Billionaire Bloomberg gave $250,000 to the political action committee backing Graham, a South Carolina Republican, for his primary battle last month, which he won comfortably, Politico said, citing a source it didn't identify.
The donation to West Main Street Values PAC is due to be revealed in financial filings that will be made public on Tuesday, the Politico source said.

Bloomberg has been backing incumbents in primaries "who have a track record of working across party lines," according to the source.
