The president posting a six and a half minute video on twitter of McCain saying 'repeal and replace Obamacare' several times. The tweet comes after McCain said he wasn't going to vote for the latest Republican attempt to repeal and replace the healthcare law, known as Graham-Cassidy.
McCain is now one of three Republicans saying they can't support the bill. The other two are Susan Collins of Maine and Rand Paul of Kentucky. Texas Senator Ted Cruz also said he may not support the bill. McCain says he's worried about Medicaid cuts.
And of course, this isn't the first time Trump has gone after McCain.
