Donald Trump went on a Twitter tirade over the weekend and in the process he managed to tweet out yet another lie.

I know. It’s just so hard to believe. Right? Actually, well … no. It isn’t. It’s Trump’s modus operandi.

While he was blasting former President Barack H. Obama, Democrats, the FBI, Hillary Clinton, H.R. McMaster and the media in the wake of the indictments over the Russian election meddling, the president accused his predecessor of doing nothing about the Russians.

Actually, sir, President Obama did do something.

I feel the need to remind Trump of that. Except that he knows it already, which makes his misstatement yet another outright lie.

Obama looked Russian strongman Vladimir Putin in the eye and told him to quit interfering in our electoral process. Then the president signed an executive order that booted several Russian diplomats out of the country, forced the closure of Russian diplomatic property and imposed strict economic sanctions on the Russians.

He sought to punish the Russians for doing what the intelligence community has confirmed what they did.

Special counsel Robert Mueller has indicted several Russians and three Russian companies for their role in the 2016 election interference. Both houses of Congress approved — with overwhelming majorities — toughened sanctions on Russia, only to have the president decline to agree to them.

In that light, Donald Trump has the gall to say that Barack Obama has done “nothing” to punish the Russians?

Liar.
