"If the impeachment provision in the Constitution of the United States will not reach the offenses charged here, then perhaps that 18th-century Constitution should be abandoned to a 20th-century paper shredder!" the quote attributed to former Rep. Barbara Jordan reads in Hillary's Friday tweet.

During an episode of Maddow earlier his week, Hillary spent just 49 seconds discussing her new "Gutsy Women" book during the roughly 21-minute appearance.

"I think this incredible series of events that we are living through right now are overwhelming in their intensity and velocity," Clinton said, "but they are also so sad and distressing to have a government that is now engaged in behavior that puts our national security at risk in order to further the president's personal and political interests.

"It is tragic," she said.

Clinton claimed Trump used funds to "threaten and intimidate the new president of Ukraine," which he recently denied.
