Conservative billionaire Timothy Mellon gives another $50 million to pro-Trump super PAC

WASHINGTON (Reuters) - Conservative billionaire Timothy Mellon, an heir of the Pittsburgh-based Mellon banking family, gave another $50 million last month to a super PAC supporting Republican Donald Trump's presidential bid, according to a federal disclosure filed on Tuesday.

The super PAC, known as MAGA Inc, has been ramping up outlays on television ads supporting Trump's candidacy and attacking Democratic presidential candidate Kamala Harris.

MAGA Inc disclosed in a filing to the Federal Election Commission that it took in more than $54 million from donors last month, with most of the money coming from Mellon. Mellon has given MAGA Inc at least $115 million this year, including a $50 million contribution in May, disclosures show.

Mellon, who lives in Wyoming and is rarely photographed, is an amateur pilot who has invested in and led transport-related companies. Forbes estimates that the Mellon family is worth some $14.1 billion.
