The New York Post put out a preview of its Wednesday cover after Donald Trump declared war on the Republican Party on Tuesday.

"It is so nice that the shackles have been taken off me and I can now fight for America the way I want to," Trump said on Twitter.

The Post's cover features the Republican presidential nominee sitting on a chair, alone, and holding a Trump-Pence balloon, with the headline "Trump at war with GOP, declares himself a PARTY OF ONE."

Trump bashed the GOP for abandoning him. He called House Speaker Paul Ryan a "very weak and ineffective leader" after the nation's highest-ranking elected Republican said he would no longer defend or campaign for Trump.

Trump later tore into Sen. John McCain of Arizona, who withdrew his endorsement of the billionaire, and continued to lash out at Republicans who had deserted him.

Here's the full cover from the Post:
