**Former New York City police chief Bernard Kerik has pleaded guilty to lying to the White House and has also said he will admit tax crimes.**Mr Kerik, who was police commissioner at the time of the 9/11 attacks in 2001, was facing a corruption trial.
He had his bail revoked two weeks ago for passing on secret pre-trial documents and has been in prison since.
He was charged with lying to the White House in 2004 while being considered for a job as homeland security chief.
Mr Kerik made the first of eight expected pleas at a court in White Plains, New York state, on Thursday.
The admissions are part of a plea bargain designed to head off three pending criminal trials on 15 federal counts. Mr Kerik had previously denied all charges.
National hero
In court, Judge Stephen Robinson warned Mr Kerik that he could face up to 61 years in prison for the offences to which he was pleading guilty.
Under the plea bargain, the prosecution has suggested the former police commissioner be sentenced to between 27 and 33 months in jail.
As well as making false statements to the White House and other federal officials, Mr Kerik is alleged to have accepted a $250,000 (£151,000) payback in the form of apartment renovations from a company to which he gave a city contract.
He is also accused of failing to report more than $500,000 (£302,000) in taxable income between 1999 and 2004 and illegally claiming charitable deductions.
Mr Kerik had been regaled as a national hero following the 9/11 terror attacks and was nominated for the post of the head of the Department of Homeland Security under the Bush administration in 2004.
But he withdrew his name from consideration for the role after he was accused of failing to pay taxes, and of having extramarital affairs.
