Heated tweets frame latest memos released on Russia investigation

Finger pointing and Twitter exchanges erupted Saturday night over a contentious political memo.

It's a rebuttal to that memo released by Republican Congressman Devin Nunes several weeks ago.

The new Democratic memo addresses claims that the FBI abused a secret surveillance process in order to spy on a Trump campaign adviser.

They insist those claims are false.

President Trump tweeted, calling the response a "disgrace" and a "total political and legal bust."

The release of the Democratic memo ends the latest chapter of the House Intelligence Committee's divisive Russia investigation.
