NYT:

Television stations across Ohio are refusing to run advertisements from the Trump campaign that are critical of Gov. John Kasich because of a technical election law violation in the ad.

New Day for America, the “super PAC” supporting Mr. Kasich, sent complaints to stations about the ad, saying that it was “falsely attacking Ohio Gov. John Kasich,” and that it did not comply with federal regulations for political advertising.

“No disclaimer appears at the end of the advertisement paid for by Donald Trump,” Matt Carle, executive director of New Day for America, wrote in the complaint. “Consequently, this advertisement is in violation of the Federal Election Campaign Act of 1971, and it must be removed from the air.”
