The Washington Post is reporting that former WWE CEO Linda McMahon donated $6 million in August and September to a super PAC supporting WWE Hall of Famer and personal friend Donald Trump.

The donations from McMahon made up nearly one-third of the nearly $18 million that Rebuilding America Now pulled in during the last quarter. She made five separate contributions, giving a final $1 million on September 22.

These donations make the former Republican Senate contender one of Trump’s biggest outside benefactors. Between 2007 and 2009, the McMahon family gave $5 million to Trump’s charitable foundation.

Last month, McMahon told the Associated Press that even though he was not her first choice for president, she is now a strong Trump backer. “Once you’re his friend, he is loyal to the end,” she said. “He’s an incredibly loyal, loyal friend.”
