It has been reported that Turkey allegedly sent weapons to ISIS and traded in ISIS oil. Furthermore, numerous media outlets have noted that Turkey has permitted thousands of ISIS terrorists to smuggle across their border into Syria and have given medical assistance to ISIS terrorists.
Not too long ago, the Turkish entourage was recorded beating Kurdish and Armenian protesters in Washington, DC. In response to this action, Senator John McCain called for the Turkish Ambassador to be booted out of the US but Trump took zero action against Turkey for this.
