​P​resident Trump blasted the New York Times in a tweet on Thursday for obstructing the GOP-backed tax reform plan and accused the newspaper of being a “pipe organ for the Democratic Party.”​

“The Failing @nytimes, the pipe organ for the Democrat Party, has become a virtual lobbyist for them with regard to our massive Tax Cut Bill. They are wrong so often that now I know we have a winner!​,” Trump posted on Twitter.

H​e also took offense at The Gray Lady’s editorial board for urging readers to reach out to their senators and tell them to oppose the tax plan.​

​”​The Failing @nytimes has totally gone against the Social Media Guidelines that they installed to preserve some credibility after many of their biased reporters went Rogue! @foxandfriends​,” Trump wrote.​

T​he New York Times editorial board on Wednesday posted on #thetaxbillhurts ​its reasons for opposing the plan and listed the names and contact information for senators – including John McCain and Jeff Flake, both Republicans of Arizona – who are still in the undecided column.

“Here is today’s editorial: GOP senators can follow the will of their donors & vote to take money from the middle class and give it to the wealthiest people in the world. Or they can vote no, to protect the public​,” one of the tweets said.​

The Republican-controlled Senate voted along party lines – 52-48 – on Wednesday to begin debate on the measure.

Trump has said he wants a bill ready for his signature by Christmas.

The House earlier in November passed their version.
