Jim Jeffrey, the United States’ retiring Special Representative to Syria and the special envoy in the fight against the Islamic State, confirmed Thursday that he and other senior administration officials routinely misled President Donald Trump on troop levels in the Middle East. Jeffrey, speaking to Defense One, explained how despite Trump’s stated promise to withdraw America from endless Middle Eastern engagements, he was able to convince the president to commit to keeping between 200 to 400 troops in the region in 2019 to “secure” oil fields held by U.S. allies and other strategic positions.  Looks like "a source familiar with the matter" to me.
