Donald Trump Jr. will venture into enemy territory Thursday when he appears on ABC’s “The View,” where even Meghan McCain, the show’s most conservative host, may take a dim view of the first son because of his dad’s attacks on her late father, Sen. John McCain.

Co-host Joy Behar made the announcement on Friday’s show, prompting a loud chorus of “ooooohhhh” from the disbelieving studio audience.

“Everyone looks so shocked. We have everyone on here,” co-host Sunny Hostin responded.

President Trump has no fans among the co-hosts, with McCain and the other house conservative, Abby Huntsman, frequently criticizing the commander-in-chief.

Whoopi Goldberg won’t even say the president’s name, and Behar is a confirmed liberal.

Trump Jr., who will appear with his girlfriend and former Fox News personality Kimberly Guilfoyle, has a book to promote: “Triggered: How The Left Thrives On Hate And Wants To Silence Us.”

Behar’s announcement came as the co-hosts were talking about Trump Jr.’s Halloween Instagram post, which included a photo of Trump Jr. in costume as a bow-and-arrow hunter and Guilfoyle as a witch.

“Witch Hunt!!! Happy Halloween folks! With all the bulls–t the Democrats are throwing out there we just couldn’t resist,” he wrote.

“Subtle,” said Behar about the “witch hunt” line, Deadline reported.

“Maybe he should have worn a prison suit,” cracked co-host Ana Navarro.

But it could be McCain who’s loaded for bear.

President Trump has repeatedly criticized her father — before and after his death — mocking the Vietnam War hero and POW for being captured after his jet was shot down.

“He’s a war hero because he was captured. I like people that weren’t captured,” Trump infamously said in 2015.

Trump was barred from McCain’s funeral, and since his death has continued slamming him at rallies for not voting to repeal ObamaCare.
