President Trump is weighing in on Russia again.

FOX's Rachel Sutherland reports from Washington:

Despite rising tensions between the U.S. and Russia, the President is sounding upbeat, tweeting: "Things will work out fine between the U.S.A. and Russia. At the right time everyone will come to their senses & there will be lasting peace!". This, after President Trump said at a news conference yesterday:

(President Trump) "We may be at an all-time low in terms of relationship with Russia."

Secretary of State Rex Tillerson arriving back in the U.S. following tense meetings with his Russian counterpart and President Vladimir Putin days after the U.S. launched airstrikes against Russia's ally, Syria, in response to a chemical weapons attack.
