(CNN) - Russia’s escalation in Ukraine dominated the political talk shows Sunday morning. American politicians and Obama administration officials are calling Russian President Vladimir Putin’s deployment of troops to the Russian-friendly Crimean peninsula the latest provocation in a troubling series of events.
It’s also the latest foreign policy challenge facing President Barack Obama, whose tenure has been plagued by international crises ranging from two wars, an unruly North Korea and uprisings in the Middle East.

(CNN) - Secretary of State John Kerry on Sunday sharply denounced Russian President Vladimir Putin's "stunning, willful" actions in Crimea, characterizing the move as an "invasion" and saying “all options are on the table” as far as a U.S. response.
"You just don't in the 21st century behave in 19th-century fashion, by invading another country on completely trumped up pretext," Kerry said, appearing on CBS's "Face the Nation."
Secretary of State John Kerry issued the following statement on the situation in Ukraine:
"The United States condemns the Russian Federation's invasion and occupation of Ukrainian territory, and its violation of Ukrainian sovereignty and territorial integrity in full contravention of Russia’s obligations under the UN Charter, the Helsinki Final Act, its 1997 military basing agreement with Ukraine, and the 1994 Budapest Memorandum. This action is a threat to the peace and security of Ukraine, and the wider region.
Washington (CNN) - A debate of more than five years could stretch even longer with Wednesday's call for a health study on the proposed Keystone XL oil pipeline from Canada.
Two Democratic senators - Barbara Boxer of California and Sheldon Whitehouse of Rhode Island - urged Secretary of State John Kerry to examine higher rates of cancer and other illness reported in places impacted by the "tar sands" oil from northern Alberta.
Their letter to Kerry sought to further delay the project that has support from Republicans, some Democrats, the oil industry and labor unions. A Pew Research Center poll in September showed 65% of respondents favored building it.
