Donald Trump just cannot stop blaming Barack Obama for mistakes he makes.

He said today that the former president never informed him about the risk he was taking by hiring Michael Flynn as his national security adviser.

D’oh! Except that the former president did warn the current president: Don’t hire this guy; he’s trouble.

Oh, but then Trump said “no one” warned him about Flynn, the retired Army three-star general who had gotten tangled up with Russians involved in that effort to undermine the U.S. election in 2016.

Trump wrote on Twitter: It now seems the General Flynn was under investigation long before was common knowledge. It would have been impossible for me to know this but, if that was the case, and with me being one of two people who would become president, why was I not told so that I could make a change?

Doggone it, anyhow! Deputy U.S. Attorney General Sally Yates also warned the president-elect about Flynn being possibly “compromised” by the Russians. Trump’s reaction was to get rid of Yates.

Flynn joined the administration as national security adviser and lasted 24 days before Trump fired him! Why? For lying to the FBI and to Vice President Pence about his relationships with those pesky Russians.

However, Trump just cannot — or will not — get his facts straight.

Barack Obama warned him about Flynn. So did Sally Yates.

The new president wasn’t paying attention!
