Jurors in the Brooklyn federal corruption trial of state Sen. John Sampson are expected to begin deliberations Thursday after hearing summations from both side Wednesday.

Sampson, a former Democratic majority leader, is charged with obstructing justice, tampering with evidence, recruiting a mole in the federal prosecutor's office and lying to the FBI to try to cover up his embezzlement of funds in foreclosure escrow accounts.

The defense contended Sampson was entrapped by the prosecution, but prosecutor Paul Tuchman told jurors the senator was "predisposed to tamper with evidence and tamper with witnesses like a fish is predisposed to swim."
