Deputy national security adviser to leave White House amid Bolton reshuffle

U.S. President Donald Trump's homeland security adviser, Tom Bossert, has resigned at the request of new national security adviser John Bolton, an administration official said on Tuesday, marking the latest departure from the White House of a senior adviser.

Bolton is replacing Army Lt. Gen. H.R. McMaster, who reportedly clashed with President Trump on foreign policy. "We thank him for his continued service", said White House deputy press secretary Lindsay Walters. Today, Deputy National Security Adviser Rick Waddell has handed in his own notice. "We wish Nadia and her family the best", he said in a statement sent to various news outlets. Anton was originally appointed by Trump's first National Security Adviser, Michael Flynn, who himself had to resign from the White House last winter because of his involvement in the investigation into Russia's meddling in the 2016 elections.

"Together, we captured your vision for a strong and confident American and developed your America first national security strategy - which turned that vision into a strategic direction for your administration", she wrote. "And I am particularly proud that you were able to submit your NSS to Congress earlier than any previous administration... on time and under budget!"

Bolton who joined on Monday has already planned to start reshaping the National Security Council team.

His departure comes after a list of others among Cabinet officials and top West Wing aides, most recently the firing of Veterans' Affairs chief David Shulkin and the resignation of Hope Hicks as communications director.

Bolton has begun reviewing the resumes of top staffers now serving on the National Security Council, a source close to the NSC told CNN.
