A report exposing how AIPAC routes money to Michigan Senate candidate Haley Stevens has the pro-Israel lobby on the defensive, bad news for the group's preferred under-the-radar tactics.

• The Detroit News found AIPAC is funneling donations to Stevens through fundraising appeals that hide the group's name, a legal but newly secretive approach.
• About a third of Stevens' larger donors also gave to AIPAC, and she has pulled in $5.5 million in pro-Israel money over her career.
• Fellow Michigan Democrat Elissa Slotkin has taken roughly $491,000 from the group and defends AIPAC's right to spend in races.
• AIPAC has shifted to quieter tactics because openly lobbying for Israel has become politically toxic amid the Gaza war.
• The group just sent a joint fundraising appeal for Stevens and Republican Susan Collins, showing it backs both parties as long as candidates back Israel.

Outlook: Expect more scrutiny of hidden pro-Israel donations as the Michigan Senate primary heats up, with challenger Abdul El-Sayed positioned as the anti-AIPAC option.
