U.S. President Donald Trump will speak by telephone with Russian President Vladimir Putin on Tuesday at 12:30 p.m. EDT, the White House said on Monday night, Reuters reported.
A senior Trump administration official said the two leaders would likely discuss the civil war in Syria, where Moscow backs the government of Bashar al-Assad and the United States supports rebels trying to overthrow him.
Trump ordered an air strike on a Syrian air base last month in retaliation for a deadly poison gas attack on civilians he blamed on Assad's government.
Russia denied the Syrian government was responsible for the sarin attack, which killed 90 people.
Trump said after the cruise missile attack that the United States' relationship with Moscow "may be at an all-time low."
