As is plentifully recalled now, beginning with Richard Nixon’s tenure in the White House liberals in the Senate and House would spend the next several decades injecting themselves into the conduct of American foreign policy when there was a Republican in the Oval Office. Senators or even former senators included John Kerry and Tom Harkin as well as Vance Hartke (Vietnam), George McGovern (Vietnam), Ted Kennedy (the Soviet Union), Christopher Dodd (Nicaragua and Syria), Robert Byrd (the Soviet Union), John Tunney (the Soviet Union), James Abourezk, (the PLO), Adlai Stevenson III (the PLO), Bill Nelson (Syria) and Joe Biden (the Soviet Union). House members aside from Jim Wright and Lee Hamilton included Nancy Pelosi (Syria), Robert Torricelli (Nicaragua) and David Bonior and Jim McDermott, the latter two interfering in Iraq. Jesse Jackson, who never served a day in Congress, has busied himself over the years intervening with dictators from Syria to Venezuela to Kosovo and more.
There’s no statute of limitations on treason.
