White House Homeland Security Advisor Tom Bossert gives an update on the federal response to Hurricane Irma.

• President Donald Trump's homeland security adviser, Tom Bossert, has reportedly been fired from his White House position by Trump's new national security adviser, John Bolton.
• Bossert, who has advised the president on terrorism, cybersecurity, and natural disaster response, has been a stalwart defender of Trump over the last 15 months.

President Donald Trump's homeland security adviser, Tom Bossert, has been fired from his White House position, Bloomberg's Jennifer Jacobs reported on Tuesday.

"The president is grateful for Tom's commitment to the safety and security of our great country," the White House said in a statement confirming Bossert's imminent departure.

This comes the day after Trump's new national security adviser, John Bolton, took office. Jacobs reported that Bolton asked for Bossert's resignation.

A former deputy homeland security adviser to President George W. Bush, Bossert has been a stalwart defender of the president's since he joined the administration during the presidential transition. He has served as the president's top adviser on terrorist threats, cybersecurity issues, and natural disasters.

Bossert has been criticized for defending the president's controversial comments about issues ranging from white supremacist protesters in Charlottesville, Virginia last summer to Russian interference in the 2016 election.

On Monday, Bossert asserted that "no voter in this country was influenced" by Russian bots during the election.

"I honestly do believe that there is a large degree of misunderstanding in the reporting and there's a whole lot of attempted politicking going on meant to try to undermine the legitimacy of the election," he told NBC News.
