When CBS News’ Mark Knoller said that President Obama had no scheduled events this weekend, he wasn’t kidding.

At least Vice President Biden made an appearance via video conference.

The president might have skipped Saturday’s national security meeting, but he did speak with Russian President Vladimir Putin on the phone.

Here’s the Kremlin’s take:

The two presidents discussed in detail various aspects of the extraordinary situation in Ukraine.

In reply to Mr Obama’s concern over the possibility of the use of Russian armed forces on the territory of Ukraine, Vladimir Putin drew his attention to the provocative and criminal actions on the part of ultranationalists who are in fact being supported by the current authorities in Kiev.

The Russian President spoke of a real threat to the lives and health of Russian citizens and the many compatriots who are currently on Ukrainian territory. Vladimir Putin stressed that in case of any further spread of violence to Eastern Ukraine and Crimea, Russia retains the right to protect its interests and the Russian-speaking population of those areas.

Update:

As expected, the White House released a picture of Obama on the phone — photographic proof that he is on it.
