President Donald Trump's political operation has reserved nearly $138 million in advertising and other spending to support Republican candidates in roughly 50 general-election races this fall.

The blitz, much of it executed over the past 10 days, comes as Republicans seek to retain control of Congress in the November midterms. The spending is tied primarily to Trump's MAGA Inc. super PAC and two newly created groups, according to media tracking data and Federal Election Commission records.

No Going Back PAC Inc. has booked more than $95 million in ads, while Safety and Affordability PAC Inc. has reserved about $27 million. MAGA Inc. itself has committed another $9 million, focused so far on the Texas Senate race. The three groups have largely divided the map, with minimal overlap in only two House districts.

The planned outlays target key Senate contests in Michigan, Ohio, and Alaska, along with numerous House races. Additional spending includes about $6.5 million on direct mail and roughly $80,000 on text messages. MAGA Inc. has amassed more than $400 million in cash on hand.

The effort follows months of limited activity from the super PAC despite its large reserves. Republicans view the new commitments as a significant boost in the fight to hold majorities in both chambers.

Details on the precise financial links between MAGA Inc. and the newer super PACs are expected in future FEC filings.
