Biden was speaking to reporters after a long day of meetings, including a private discussion with Turkish President Recep Tayyip Erdogan.

The two leaders spent in total more than an hour together.

Biden thanked NATO Secretary General Jens Stoltenberg for leading “a very successful NATO summit.”

But he warned, the “democratic values that undergird our alliance are under increasing pressure, both internally and externally.”

“Russia and China are both seeking to drive a wedge in our transatlantic solidarity,” Biden said.
