(AP) - Gov. David Paterson is scheduling an unusual Sunday press conference as he tries to help senators end a power struggle that has gridlocked the chamber in the last two weeks of the regular session.

Paterson says he will compel senators to attend a special session later this week if they don't find a way to open the Senate for business. The regular session is scheduled to end Monday.

A Republican-dominated coalition says it seized power in a contested June 8 revolt over the Democratic conference that won a majority of seats in the November election. The Democratic conference has boycotted the coalition-run sessions in the last two weeks.

Democratic Sen. Pedro Espada, who is a leader in the coalition, says he expects an agreement to be struck before Monday.
