NEW YORK (CNN/Money) - Lawrence Lindsey, a top economic advisor to President Bush, is preparing to leave the post, according to a published report.

The Washington Post reported Wednesday that Lindsey, the director of the National Economic Council, is making subtle inquiries about returning to private-sector work on Wall Street. The paper quotes unidentified senior congressional Republican aides as saying that Lindsey's aides have already begun to look for jobs on Capitol Hill, while economic aides in Congress are sending resumes to the NEC in anticipation of a change in leadership.

Lindsey was Bush's main tutor on economic issues during his 2000 campaign, and was seen as the architect of the president's 10-year, $1.35 trillion tax cut that is a center piece of his legislative agenda.

White House spokeswoman Claire Buchan told the Post, "The president has confidence in his economic team, and we never discuss specific personnel matters."

Tuesday evening Securities and Exchange Commission Chairman Harvey Pitt submitted his resignation amid criticism of his stand on cleaning up corporate corruption.

The Post said that the other two high-profile members of Bush's economic team - Treasury Secretary Paul O'Neill and Council of Economic Advisers Chairman R. Glenn Hubbard, appear to be more secure in their posts than Lindsey and Pitt.
