President Trump’s Department of Justice asked a judge to give final approval of the $69 billion merger between CVS and Aetna on Monday — but there’s only a 50 percent chance of the judge agreeing, insiders said.

Drugstore company CVS Health did close its planned merger with insurance giant Aetna in November after getting the DOJ’s seal of approval and agreeing to sell some of Aetna’s businesses as a merger condition. But DC District Judge Richard Leon, who needs to clear the deal, has not allowed the companies to fully integrate and said he is not going to be a rubber stamp — leading DOJ insiders to give their latest request a 50 percent shot of success, sources told The Post.

There’s concern the deal will lead to higher drug prices.
