KANSAS CITY, Mo. (AP) — President Barack Obama says the House GOP's vote to file a lawsuit against him is taking away from time they could be spending on issues that are important to the American people.

Obama is calling the lawsuit accusing him of exceeding his powers in enforcing his health care law a "political stunt." He says the only reason he's taking action on his own is because Congress isn't doing anything to help him.

A party-line vote on pursuing the lawsuit is expected when the House takes up the measure Wednesday afternoon.

Obama took a sharply partisan tone in his remarks ahead of the vote, saying Republicans should "stop just hating all the time". He says he knows they're not happy that he's president, but says they only have a few years left until they "can be mad at the next president."
