U.S. President Donald Trump said on Friday he will nominate U.S. Deputy Secretary of State John Sullivan to be the U.S. ambassador to Russia.
If confirmed by the Senate, Sullivan would be the top U.S. diplomat in Russia at a particularly challenging time for Trump's presidency, which is facing an impeachment inquiry after Trump pressed Ukrainian President Volodymyr Zelenskiy to investigate one of Trump's domestic political rivals.
