Tulsi Gabbard is resigning as President Donald Trump‘s director of national intelligence, she announced Friday.

Gabbard, in a resignation letter addressed to Trump, said she has to step down in order to support her husband, Abraham Williams, who has “recently been diagnosed with an extremely rare form of bone cancer.”

“I cannot in good conscience ask him to face this fight alone while I continue in this demanding and time-consuming position,” she wrote in the letter dated Friday.

Her resignation is effective June 30, she wrote.

Fox News first reported Gabbard’s resignation.

The White House did not immediately respond to CNBC’s request for comment.
