A heavy blow was delivered to the Trump administration yesterday--

Within a matter of minutes, the President's former personal attorney Michael Cohen plead guilty to eight counts of fraud and tax evasion in New York City, and meanwhile in Alexandria, Virginia, former Trump campaign chairman Paul Manafort was convicted on eight counts of various financial crimes.

This is a major victory for special counsel Robert Mueller--the head of the Russia investigation-- but potentially a huge problem for the president and his Republicans vying to maintain control of Congress this fall.
