US National Security Adviser Michael Flynn has resigned on Monday. The sudden resignation from US President Donald Trump’s adviser has come following the White House alleging the NSA of having connections with Russia.

“Unfortunately, because of the fast pace of events, I inadvertently briefed the vice president-elect and others with incomplete information regarding my phone calls with the Russian ambassador. I have sincerely apologized to the president and the vice president, and they have accepted my apology,” Flynn said in his resignation letter.

The White House raised doubts over Flynn’s discussion regarding the lifting of US sanctions on Russia. The US authority released a statement just after 11 pm in which it stated that the resignation of Michael Flynn has been accepted. In addition to the acceptance confirmation, the statement also named Keith Kellogg as the acting  NSA.

Kellogg, the acting successor of Michael Flynn, is a retired general who has been the chief of staff of the White House National Security Council. Meanwhile, Trump would decide on the most suitable person capable of holding the position. The names that are being considered fit for the NSA post include Kellogg, former CIA director retired general David Petraeus, and former USCentral Command’s deputy commander Robert Harward.

Trump’s key counsellor Kellyanne Conway declared before Flynn’s resignation that Trump had “full confidence” in the adviser. The White House also alleged the president of “evaluating the situation” after authorities found the NSA of sharing an alleged link with Russia.

Background Behind Doubts Raised against Michael Flynn

The doubts over Michael Flynn’s links with Russia were raised after the US Justice Department warned the White House to be careful with the NSA. According to reports, Flynn contacted Russia before Trump took charge of the States on lifting US sanction. However, the department allege Flynn might not have done so and might have misled the nation.

The warning from the justice department came after the then-acting US Attorney General Sally Yates told the White House in January that she had a doubt over Flynn’s communications with Russian ambassador to the US. “The acting attorney general informed the Trump White House late last month that she believed Michael Flynn had misled senior administration officials about the nature of his communications with the Russian ambassador to the United States, and warned that the national security adviser was potentially vulnerable to Russian blackmail, current and former U.S. officials said,” The Washington Post reported.
