UPDATE 1-Sale of ex-Trump aide Scaramucci's firm on track - exec

(Adds details from Nolte video, background on sale)

BOSTON, Sept 18 (Reuters) - The sale of former White House communications director and investor Anthony Scaramucci's SkyBridge Capital to a consortium that includes a Chinese buyer is still on track, with the closing date set for month's end, the firm's chief investment officer said on Monday.

New York-based hedge fund SkyBridge Capital is still waiting for approval from one agency, CIO Ray Nolte said in a video sent to reporters on Monday, without naming the regulator.

"We are hopeful that will come through in fairly short order and as soon as it does we will be able to move to the close," he said.

A SkyBridge spokeswoman said the group is waiting for approval from the Committee on Foreign Investment in the United States.

"We are down to one that we are waiting on," Nolte said about the approval process. Looking ahead to a close, Nolte said it was hard to specify a date but "at this juncture we'd probably be looking at something in September as a targeted closing date."

In May, Scaramucci told Reuters he thought the deal would probably close in June.

HNA Capital U.S., a unit of Chinese conglomerate HNA Group, and RON Transatlantic EG said in January they had agreed to purchase a majority stake in SkyBridge.

By cutting ties to SkyBridge, Scaramucci, a prominent Wall Street hedge fund investor, was paving a path to the White House, which he had hoped to join as an adviser soon after the inauguration.

He arrived in July as White House communications director but was fired a week later after an obscenity-laced telephone interview with a New Yorker magazine writer. (Additional reporting by Lawrence Delevingne; Editing by Leslie Adler and Jeffrey Benkoe)
