President Trump questioned Senate Minority Leader Charles Schumer's (D-New York) proposal that all 100 senators meet to talk about ObamaCare.
While the president was preparing to take pictures with the World Champion Chicago Cubs, a reporter shouted a question regarding Schumer's offer.
Trump paused, appearing to think about the idea, and said he had to "find out if he's serious."
"He's done a lot of bad talking," Trump said. "He hasn't been serious. ObamaCare is such a disaster - such a wreck. He wants to save something that's hurting a lot of people."
"He just doesn't seem like a serious person," Trump said.
Schumer sent a letter to his Republican counterpart, Mitch McConnell, asking to meet to talk health care.
"The U.S. Senate has long been considered the world’s greatest deliberative body and, as members of that body, we should each support open and robust debate," Schumer wrote, according to Politico.
Schumer has recently attacked Republicans' bill as one that would hurt scores of Americans.
