“[MSNBC ignored Trump’s speech because] there is a cost to us . . . to knowingly broadcast untrue things.”

— MSNBC’s Rachel Maddow, Tuesday

We say: Sounds like the liar who swears he never lies. Fact is, MSNBC spouts plenty of untruths itself.

And Maddow’s a foremost fibber (recall her endless false Russia Collusion mania?).

This sudden supposed fear of spreading misinfo is just leftists’ new go-to excuse: The truth is that the network didn’t air President Donald Trump’s post-indictment speech simply because its staff hates him and doesn’t want anyone hearing his claims of selective prosecution.

“Two-year-olds should’ve been required to wear a mask. It would be child abuse for parents not to do that.”— Rep. Jerrold Nadler (D-NY), Wednesday

We say: Nadler still won’t follow the science.

Two-year-olds were never at much risk of COVID, and most masks — as studies, including the gold-standard Cochrane review of mask-mandates’ effectiveness, show — made little or no difference in stopping the bug’s spread.

Forcing 2-year-olds to mask up, as Nadler would like, is the real child abuse.

“Why comparisons of Trump’s actions with the Bidens’ or Clinton’s fall flat”

— The Washington Post, Friday

We say: WaPo “analyst” Philip Bump’s column might not seem quite so ridiculous if he’d gotten his facts straight.

He claims, for example, “the FBI appears not to have thought” allegations that a Ukrainian businessman bribed President Biden would “pan out” back when “Trump appointee William P. Barr was running the Justice Department.”

Except Barr himself says Justice never dropped its probe of those allegations under him.

Even so, the column is little more than lame spin: True, President Donald Trump’s actions weren’t exactly like those of the Bidens and Hillary Clinton, as Bump notes.

But they all clearly broke the law repeatedly.

Yet only Trump’s been indicted, while Hillary skated and the Biden probe is inexplicably stalled.

“So we [Xi Jinping and Biden] traveled . . . 17-, 18,000 miles together in China and the United States.”

— President Biden, Tuesday

We say: Biden’s made this wacky boast about himself and Chinese President Xi Jinping often, but it’s not remotely true; even the liberal Washington Post gives it three Pinocchios.

Then again, he also claimed this week that the US has “plans to build a railroad from the Pacific all the way across the Indian Ocean” — and “soon, Africa will have 1 billion people” (it topped 1 billion in 2009).

Is he senile? Or just an idiot?
