The lede in The Hill:

The U.S. Chamber of Commerce received an $800,000 wire transfer from billionaire donor Hank Meijer days after it endorsed his son, then-Rep. Peter Meijer (R-Mich.), in a contentious 2022 primary, according to previously unreported internal emails reviewed by The Hill.

. . .

But because the ad — titled “Thank you, Rep. Peter Meijer” — does not explicitly advocate for his election or defeat, the pro-business lobbying giant did not have to legally disclose the donation from Hank Meijer, the co-chair and CEO of the Meijer chain of superstores. It also did not have to disclose any other potential contributions behind the $1.8 million it told the FEC it spent on “electioneering communications” that cycle.
