The politicians during that time (Watergate) were so different from today's species
The Nixon White House thought that
Rep. Larry Hogan Sr. was firmly in their camp, because he repeatedly said that the White House should be able to present evidence and have general due process. Nixon and his family, including his daughters, had campaigned for Hogan, helping him first get elected in 1968. Hogan didn't like being in this situation before the House Judiciary Committee.
But Hogan had been an FBI agent, and that was a big selling point that helped get him elected in 1968 on the "Law & Order" issue. There were riots after the murder of Martin Luther King Jr, the assassination of Robert F.Kennedy, numerous protests of the Vietnam War, including riots at the 1968 Democrat convention in Chicago. The FBI was facing heavy criticism in this era for its hiring practices and general conduct. Once elected to Congress, Hogan found himself constantly defending the good things that the FBI had done.
In the Watergate "smoking gun" tape, from June 23, 1972, six days after the Watergate break-in, Nixon agrees that administration officials should approach Richard Helms, Director of the CIA, and Vernon A. Walters, Deputy Director, and ask them to request L. Patrick Gray, Acting Director of the FBI, to halt the Bureau's investigation into the Watergate break-in on the grounds that it was a national security matter. Manipulating the FBI to get away with committing crimes was not going to sit well with Hogan, given his background.
