(NBC NEWS) President Donald Trump’s personal lawyer, John Dowd, revealed Monday a potential legal defense in the ongoing Russia probe, claiming that a president cannot obstruct justice.

“The president cannot obstruct justice because he is the chief law enforcement officer under (the Constitution’s Article II) and has every right to express his view of any case,” Dowd told NBC News Monday.

Dowd added that the president’s weekend tweet — which many have argued strengthened a potential obstruction of justice case for special counsel Robert Mueller — “did not admit obstruction.”
