Battle lines appear to be tightening over Russia's potential invasion into Ukraine

Battle lines appear to be tightening over Russia's potential invasion into neighboring Ukraine — and NATO and other European leaders are pleading for diplomacy ahead of face-to-face talks between the U.S. and Russia in Geneva next week.

The White House is pushing back against a report that said the Biden administration might be willing to consider lowering troop levels in Eastern Europe if Russia would pull back its forces from near Ukraine, Christina Ruffini reports for "CBS Saturday Morning." A senior State Department official told reporters on Friday, "I want to be crystal clear that that is not accurate."

But the Putin problem remains.
