Donald Trump blocks release of Democratic memo on Russia probe

In a letter to the chair of the House Intelligence Committee on Friday, White House counsel Don McGahn says the memo "contains numerous properly classified and especially sensitive passages."

The Democrats' memo aimed to counter a Republican-drafted one the president declassified and released.

However, portions of the memo "would create especially significant concerns for the national security and law enforcement interests," McGahn wrote.

FBI chief Christopher Wray and Deputy Attorney General Rod Rosenstein in a separate letter indicated that releasing this material would present concerns for the "protection of intelligence sources and methods, ongoing investigations and other similarly sensitive

information."
