THE BRONX - Ex-state Sen. Pedro Espada Jr. claims he is innocent even after pleading guilty to several charges.

Espada is proclaiming his innocence thanks to a polygraph test, which took place last week. The lie detector test lasted four hours with about a dozen questions.

The former senate majority leader wanted to have the test done on himself, and says the questions relate to his case. Prosecutors say Espada funded a lavish lifestyle off taxpayer dollars from his Soundview Healthcare Network.

He pleaded guilty to the charges through a plea deal, but says he was not given a fair trial. If Espada violates the plea deal and tries to appeal, the judge may decide to give him the maximum penalty of 43 years in federal prison.

Espada is scheduled to be sentenced on June 14.
