Trump responds to Obama's speech by calling him boring: 'I watched it but I fell asleep'

After his predecessor took the unusual step of criticizing him by name in a speech Friday, President Donald Trump shot back with childish attacks and blatant lies.

President Barack Obama has extensively criticized Trump, including his relationship with Russian President Vladimir Putin and his attempts to corruptly influence the Justice Department, while defending his own legacy.

"I'm sorry, I watched it but I fell asleep," Trump said Friday about Obama's speech. "I've found he's very good, very good for sleeping."

Trump also claimed, as he has in the past, that economic indicators were terrible under Obama but excellent during his own presidency. However, the data, in fact, show that Obama oversaw a steady, if somewhat disappointing, economic recovery, and those trends have continued in Trump's first term.
