The Republican National Committee is gearing up to go after Bill Clinton’s half-brother, Roger, with questions about a house purchased in California for $875,000, according to a memo first obtained by ABC News.

The memo takes a keen interest in longtime Clinton aide, Justin Cooper.

“Cooper is Bill Clinton’s body man turned wheeler-dealer. He’s gone from making a modest salary working in the White House to setting up an LLC just to buy a home for the president’s brother to live in,” the memo said.

“But how and why has he suddenly become Roger Clinton’s real estate agent and financier? Why would Cooper, despite living in Manhattan, be the one to purchase a home in California that was intended as someone else’s residence? And how did he get the money to do it?” it asked.
