1. Ukrainian Prime Minister Arseniy Yatsenyuk spoke from Kiev with David Gregory on NBC's "Meet the Press." Yatsenyuk said Russia is a "threat to the globe," and that Russian President Vladimir Putin has "a dream" to restore the Soviet Union. Appearing after Yatsenyuk, Sen. Bob Corker (R-Tenn.), the ranking Republican on the Senate Foreign Relations Committee, said he believes that eastern Ukraine will be lost to Russia if the U.S. does not take a more forceful stance.

2. U.S. Ambassador to Ukraine Geoffrey Pyatt also appeared from Kiev, on CNN's "State of the Union." Pyatt said a pact reached this week in Geneva to de-escalate the crisis in Ukraine is "the "best chance that we've got" to do so diplomatically."

3. Retired Supreme Court Justice John Paul Stevens told George Stephanopoulos on ABC's "This Week" that it's okay for Supreme Court justices to take politics into account when deciding whether to retire. ""It's an appropriate thing to think about your successor, not only in this job," he said.
