It’s apparently not “mansplaining” when a liberal guy silences a female Trump appointee. At least, that’s one takeaway from Sen. Cory Booker’s lecture to Homeland Security Secretary Kirstjen Nielsen.

The Jersey Democrat was theoretically questioning her at a Tuesday hearing on immigration reform, but he was too busy thundering that “he hurt” and had “tears of rage” over President Trump’s reported “s - - thole countries” remark to actually ask her anything.

In answer to other queries, Nielsen had repeatedly said she didn’t recall Trump using the word at that meeting last week.

“Your silence and your amnesia are complicity,” Booker preened. “For you not to feel that hurt and that pain and to dismiss some of the questions of my colleagues, saying, ‘I’ve already answered that line of questions,’ when tens of millions of Americans are hurting right now because they’re worried about what happened in the White House — that’s unacceptable to me.”

Nielsen sat stone-faced as Booker filibustered on, pounding the table and displaying his best “angry face.”

The senator plainly hoped his antics would go viral among 2020 Democratic voters, without the least concern about the woman he was using as a prop and punching bag.

The only silver lining was that Booker’s show involved no outright fiction like the tear-filled tales he used to tell about his nonexistent Newark drug-dealer pal “T-Bone.” But it’s still a pathetic performance for a US senator.
