Trump fires John Bolton as national security adviser

U.S. President Donald Trump on Tuesday announced that he had fired National Security Advisor John Bolton, citing strong disagreement between the pair.

"I disagreed strongly with many of his suggestions, as did others in the Administration," Trump said on Twitter, adding that he will name a replacement next week.

Trump's announcement came an hour after the White House had announced a press briefing, set to feature Bolton and Secretary of State Mike Pompeo.

Bolton’s replacement will be the fourth of the Trump administration. Bolton is known for softening Trump’s plans, announced in December 2018, for a speedy withdrawal of U.S. forces from Syria, and setting down conditions that would require the extended presence of U.S. troops.

Bolton maintained frequent contact with Turkish Presidential Spokesperson Ibrahim Kalın. The pair in a phone call earlier this month discussed an array of issues, including the proposed safe zone in northern Syria.

Turkish President Recep Tayyip Erdoğan in January refused to meet with Bolton upon his arrival in Ankara over his comments on Kurdish forces in Syria, calling the remarks a "serious mistake."

Bolton, during a visit to Israel days before, had said that U.S. forces would not leave Syria until the Islamic State (ISIS) was fully defeated and the Trump administration received assurances that U.S.-backed Kurdish fighters would be protected.

Turkey sees Syria’s U.S.-backed Syrian Kurdish militia, the People’s Protection Units (YPG), as security threat linked to Kurdish insurgents at home.
