Republican presidential front-runner Donald Trump on Tuesday attacked Wisconsin Gov. Scott Walker's endorsement of rival Ted Cruz, telling supporters that "he certainly can't endorse me after what I did to him in the race, right?"
"So, Walker came out today," Trump said at a rally in Janesville, Wis. "I wrote down notes about Wisconsin."
Some audience members then booed the Republican front-runner before he slammed
Walker's endorsement earlier Tuesday. The governor quit the 2016 race last July.
Trump then rattled off statistics about the Badger State's economy during Walker's tenure, including a $45 billion state debt, 20,000 fewer people in the labor force versus seven years ago and 800,000 food-stamp recipients.
"Am I going to say he's doing a great job?" Trump asked. "He's not doing a great job."
Trump posted this on Twitter earlier Tuesday:
