Kellyanne Conway has announced she is leaving the White House to devote more time to family, in a statement on Sunday night (local time).
US President Donald Trump's adviser announced she will be leaving at the end of August, less than three months from the election.
"I'm leaving the White House. Gratefully and Humbly," Conway said in a statement posted on social media.
"The past four years have allowed me blessings beyond compare as a part of history on Election Night 2016 and as senior counselor to the President."
Conway was Trump's campaign manager during the 2016 election, and was the first woman to run a successful US presidential campaign.
Her husband, George Conway also announced that he was withdrawing from The Lincoln Project - a group formed by anti-Trump Republicans - as they made a mutual decision to spend more time with their family.
'We disagree about plenty but we are united on what matters most: the kids," Kellyanne said.
"This is completely my choice and my voice. In time, I will announce future plans. For now, and for my beloved children, it will be less drama, more mama."
