Former Secretary of State John Kerry said Friday that the Republican decision to release a memo that details the abuse of surveillance authorities under the Obama administration is an "ugly" reminder of the Watergate era.

"The Nunes memo is dangerous, ugly, and an assault on the integrity of the institutions of our country," he tweeted. "I lived through Watergate/Nixon: America pays a very steep price when a political party tries to undermine the institutions that hold us together ..."

"In Watergate, the difference was, regardless of Party, eventually leaders on both sides said 'enough,'" Kerry added. "The adults in the House GOP know better and need to act like it."

Kerry and most other Democrats fumed at the decision to release the memo, which said the basis for spying on a former member of President Trump's team was based on an unverified document paid for by Democrats.
