World politics, including the conflicts in Ukraine, Syria and Iraq, will dominate the Sunday television news talk shows.
The discussion comes amid NATO assessments that at least 1,000 Russian troops have crossed into Ukraine to support separatists.
Also this past week, Ukrainian President Petro Poroshenko announced that Russian forces were on the country's soil.
The U.S. accused Russia of having "outright lied" about military activity in Ukraine during an emergency meeting of the United Nations Security Council. President Obama, however, has ruled out U.S. military involvement in the conflict.
When it comes to the struggle against the Islamic State in Iraq and Syria, Obama said he is building a "broader regional strategy" to deal with the issue. He expressed confidence in "rooting out a cancer" that is the violent movement.
