Progressive host Cenk Uygur confirmed he personally wrote a controversial ad attacking Republican Mike Rogers over Israel aid in Michigan's contested Senate race, a reveal that matters for anyone watching whether outside political money is swaying tight races.

• Uygur says his group, Rebellion Impact, created the ad hitting Rogers for supporting billions in aid to Israel while taxpayers foot the bill.
• He claims cable news outlets criticized the ad but refused to let anyone from his group respond on air.
• The ad contrasts Rogers with Democratic opponent Abdul El-Sayed, framing the race as a test of who US aid dollars really serve.
• Separately, Trump said he would halt aid to Israel, and Trump himself linked that move to political pressure building around the Michigan race.
• Uygur dismissed the idea that ringing a donation bell does anything beyond funding his own show, poking fun at his own fundraising pitch.

Outlook: Results in the Michigan Senate race will be watched as a signal of how much this ad fight and the Israel-aid debate swayed voters.
