Presidential candidate and former Vice President Joe Biden demanded that Turkey "stay out" of the Nagorno-Karabakh conflict between Azerbaijan and Armenia, in which Turkey has supported the Azeris. Eliot Engel, chairman of the House Foreign Affairs Committee, called the influence of third party actors like Turkey "troubling". In a letter to Secretary of State Pompeo, Senate Foreign Relations Committee ranking member Bob Menendez, Senate Minority Leader Chuck Schumer, and several other lawmakers called for the Trump administration to "immediately suspend all sales and transfers of military equipment to Ankara." As for the result, relations between the United States to Turkey and Azerbaijan further worsened, with Turkey accused the United States of sending weapons and supplies to Armenia, which Washington denied.
