Yep they both do it.
Jon Stewart forgot to also say that Senator Kennedy did it under Regan and made a deal with the Soviet Union to undermine Regan's deal.

Ted Kennedy s Soviet Gambit - Forbes
In 1983, the late Sen. Ted Kennedy concocted a scheme meant not only to undermine President Ronald Reagan’s nuclear arms reduction talks with the Soviet Union, but to propel the senator into the catbird seat for the 1988 presidential election.
The Kennedy plan was only revealed after a treasure trove of documents from the dissolved Soviet empire was released. London Times reporter Tim Sebastian brought the story to the world in 1991, revealing a
memo from then-KGB head Viktor Chebrikov to the Soviet leader, Yuri Andropov.
