Donald Trump just undercut his own party on the debt ceiling. It was deliberate.

President Donald Trump just shivved his own party’s congressional leadership heading into the biggest month of legislative business this year.

Trump baffled congressional Republicans, and even some in his own administration, by quickly siding with Democratic leaders on a deal to fund the government and raise the federal debt ceiling for the next three months. It was a deal that his own party, led by Speaker Paul Ryan (R-WI), opposed, including in a public statement just hours before a closed-door White House meeting between the president, fellow congressional leaders, and Treasury Secretary Steve Mnuchin.

For all his famed negotiating skills, Trump emerged from the meeting having handed Democrats a legislative triumph. But according to sources close to Trump, the president was more than willing to cut the deal because he has grown tired, if not resentful, of Republican leaders on Capitol Hill.
