ST. PAUL, Minn. (AP) — A Minnesota House Democratic leader is apologizing after a video showed him making an obscene gesture at a Republican lawmaker who was announcing a tentative deal on affordable insulin at the state Capitol.

House Majority Leader Ryan Winkler of Golden Valley is seen off to the side extending a middle finger toward Chaska Sen. Scott Jensen, the lead Senate GOP negotiator on the insulin bill.

Minnesota Senate Republicans tweeted a video of Winkler’s gesture Tuesday, saying it look like Winkler “didn’t like our message today” on insulin.

Winkler apologized on Twitter, saying his son has Type 1 diabetes and that “after months in which Senate Republicans blocked the emergency insulin bill, it was also a poor form of them to claim credit alone after we are all on the edge of a deal.”
