Newt Gingrich: Watergate is only one data point in mapping out how the establishment tries to destroy its enemies

Newt Gingrich : The FBI began watching Rev. Martin Luther King Jr. after the Montgomery Bus Boycott in 1955 as part of its domestic counterintelligence program, known as COINTELPRO.

He says the FBI didn’t just monitor and wiretap King; as he grew more powerful and influential, the bureau’s efforts grew more desperate.

Gingrich: When conservatives talk about the weaponization of the FBI and the Justice Department , they should include the astonishing story of our government's long vendetta against the civil rights activist.

Rep. Tip O'Neill was an advance man in Missouri for John F. Kennedy during the 1960 Presidential campaign.

Jimmy Breslin wrote about it in his 1975 book How the Good Guys Finally Won: Kennedy illegally took campaign cash for his personal use.

The most startling example of the Nixon set-up may be the story of Howard Hunt , a key member of the Watergate scandal.

Richard Usdin : The fix was in for the Watergate investigation to look at past presidential law-breaking, not just Nixon .

He says the investigation’s refusal to examine the Johnson and Kennedy activities was deliberate.

Usdin says it would have made clear that Watergate was similar to Johnson 's earlier activity — although on a much smaller scale and less intrusively.
