Senior White House officials have resigned after supporters of President Donald Trump stormed Capitol Hill on Wednesday.
The chief of staff to First Lady Melania Trump, Stephanie Grisham, has expressed on Twitter her intention to resign, saying, "It has been an honor to serve the country in the White House."
Grisham served as White House press secretary before becoming chief of staff to the first lady.
She did not mention the reason to leave the post, but media reports say the occupation of the capitol building by Trump supporters is behind her decision.
White House deputy press secretary Sarah Matthews also resigned on Wednesday, saying she was deeply disturbed by what she saw on the day.
Media outlets say other White House staffers, including national security adviser Robert O'Brien, are considering resigning from their positions. O'Brien's deputy, Matthew Pottinger, has also resigned.
White House officials appear to be increasingly distancing themselves from the president in the wake of the unprecedented incident in the nation's capital.
