White House press secretary Sarah Huckabee Sanders says it is "closer to $6 [million]", but Trump says she is wrong, adding the money was "spent through a law firm".
The firm, Perkins Coie, was working on behalf of Clinton and the Democratic National Committee, and hired Fusion GPS in 2016.

Omarosa said it was inappropriate for the president to turn a discussion of a deadly attack on service members into a punchline, noting that Trump's condolence call to the widow of one of the troops killed in Niger later turned controversial after the widow said the president was insensitive and didn't recall her husband's name.
After the release of the secretly recorded conversation, Trump fired back calling Manigault "wacky" and "vicious, but not smart" also claiming General Kelly told him "she was a loser and nothing but problems".
