Ex-Obama official accuses Trump of obstruction of justice after he tweets about Mike Flynn plea deal

An ex-Obama administration official who worked in the Department of Justice accused President Donald Trump of obstruction of justice on Saturday after the president tweeted about the Michael Flynn plea deal.

What did he say?

Responding to comments Trump made, Matthew Miller, the DOJ spokesman under Obama, wrote on Twitter: "Oh my god, he just admitted to obstruction of justice. If Trump knew Flynn lied to the FBI when he asked Comey to let it go, then there is your case."

Miller was specifically responding to Trump's claim that he personally fired Flynn after becoming aware that Flynn, who was Trump's national security adviser, lied to Vice President Mike Pence and the FBI.

What did Trump say?

After telling reporters this morning at the White House that he wasn't concerned about Flynn's cooperation with Mueller, Trump tweeted:

But where's the 'obstruction of justice?'

While testifying before Congress in June, former FBI Director James Comey admitted that Trump once pressed him to "let it go" referring to the FBI's Flynn probe.

From CNBC:

In his prepared testimony, Comey recalled that, at that Oval Office meeting, the president said: "I hope you can see your way clear to letting this go, to letting Flynn go. He is a good guy. I hope you can let this go."

According to Miller, Trump committed obstruction of justice because he told Comey to drop the investigation after knowing that Flynn had lied to the FBI, as Trump confirmed Saturday morning.

Barbara McQuade, a former U.S. attorney, doubled down on Miller's tweet in comments to the Daily Beast.

"This tweet makes it clear that Trump knew at the time that he made his request to Comey to let the investigation go that Flynn had lied to the FBI, which is a criminal offense," she told the publication.

For his part, Trump has maintained since day one that he committed no wrongdoing.
