NEW YORK/WASHINGTON, April 17 (Reuters) - U.S. President Barack Obama stood by his auto task force head on Friday, saying Steven Rattner had not been accused of any wrongdoing related to an alleged pension kickback scheme in New York.

Rattner was one of the executives involved with payments being probed by New York state and federal regulators in the alleged scheme, a source familiar with the situation said on Friday.

He is the person only identified as a "senior executive" of Quadrangle Group in the U.S. Securities and Exchange Commission complaint against two former New York political officials and others, the source said. His identity was earlier reported by The Wall Street Journal and The New York Times.

The "senior executive" met with a consultant, and then the firm paid a $1.1 million fee after receiving an investment from New York's pension fund, the complaint said.

Neither Rattner nor Quadrangle, a private equity fund he co-founded, has been accused of any wrongdoing.

The White House said Obama had full confidence in Rattner.
