Trump’s presidency has lurched from crisis to crisis since he took office less than two years ago, but Thursday was a landmark day of chaos that appeared to test the resolve of even senior Republican backers in Washington.
Defense Secretary James Mattis, a widely respected figure seen as a stabilizing influence inside the administration, handed in his resignation after arguing with Trump over foreign policy in a White House meeting.
Mattis then released a letter that showed fundamental policy differences between the two men and implicitly criticized Trump’s disregard for allies abroad.
Also on Thursday, Trump resisted pressure to stand down from a decision to withdraw U.S. troops from Syria, made plans to pull American forces out of Afghanistan and pushed the U.S. government toward a shutdown over funding for a border wall.
To top it all off, U.S. share prices tumbled as investors worried the looming shutdown, slower economic growth and the Federal Reserve’s projections for more interest rate hikes next year.
Even some of Trump’s friends showed deepening worry about where his administration is heading at the halfway point of his term.
Senator Lindsey Graham, a close ally and frequent golf partner, on Thursday praised Mattis, publicly urged Trump to reconsider the Syrian pullout and warned that withdrawing troops from Afghanistan could ultimately lead to another attack on America similar to the one on Sept. 11, 2001.
“I believe you are on course to make the same mistake President (Barack) Obama made in Iraq ... It will turn out no better for you than it did for him.” Graham tweeted of the Syria move.
Graham said the conditions in Afghanistan made troop withdrawals a high-risk strategy. “If we continue on our present course we are setting in motion the loss of all our gains and paving the way toward a second 9/11.”
Senate Majority Leader Mitch McConnell issued a statement expressing grave reservations about why Mattis left.
“I am particularly distressed that he is resigning due to sharp differences with the president on ... key aspects of America’s global leadership,” he said.
It was a vivid reminder of the early months of Trump’s White House, when he fired his first national security adviser, Michael Flynn, after only days in office, fired then-FBI Director James Comey and launched a travel ban against majority Muslim countries that was blocked by the courts.
