Melania Trump has barely been seen on the campaign trail this year. One of the few times she has appeared at a political event, she’s received a six-figure paycheck – a highly unusual move for the spouse of a candidate.

The former first lady spoke at two political fundraisers for the Log Cabin Republicans this year, and she was paid $237,500 for an April event, according to former President Donald Trump’s latest financial disclosure form. The payment was listed as a “speaking engagement.”

Trump’s latest disclosure form said Melania Trump was paid by the Log Cabin Republicans for the April fundraiser. But it’s a mystery who actually cut the check: Charles Moran, president of the Log Cabin Republicans, told CNN earlier this month the group did not put up the money for her to speak, and the disclosure form did not give any more information about the source of the payment.
