Sarah Huckabee Sanders found herself on the hot seat Thursday after President Trump blamed her for the mushrooming scandal over his alleged affair with porn vixen Stormy Daniels, a new report said.

Trump was furious with Sanders over her answers during a press briefing Wednesday over the tawdry accusation, in which she repeated the president’s denials and alluded to a “private” arbiter’s supposed ruling that barred the former adult film actress from talking about their tryst, CNN reported.

“POTUS is very unhappy,” a source told the network. “Sarah gave the Stormy Daniels storyline steroids yesterday.”

Sanders said the arbitration went “in the president’s favor” — apparently the first time the White House had acknowledged that the nondisclosure deal cooked up by Trump’s lawyer, Michael Cohen, existed.

Daniels, whose real name is Stephanie Clifford, sued Trump this week, saying the fact that he had not signed the nondisclosure agreement under the agreed-upon alias David Dennison meant that it was invalid and that she could blab away about their dalliance.

She has said that she and Trump had it going on in 2006 while Trump’s third wife, Melania, was home caring for their infant son, Barron.

Cohen said Trump denies that there were any shenanigans between the two.
