ALBANY— Gov. David Paterson said Friday he’s withholding the pork-barrel grants senators are used to doling out, punishing them for failing for a fourth straight day to get to work as he ordered. With evenly divided factions disputing majority control of the chamber, senators met again in two separate consecutive sessions, the first attended by most of the Democrats on one side, the second by most of the Republicans on the other. Neither passed legislation. In the only action, the Democrats held a moment of silence for Michael Jackson and Farrah Fawcett. The Republican-led coalition did not. Both met and adjourned within minutes. ‘‘Today, New Yorkers went to work. They clocked in, and they didn’t clock out, despite the fact that it’s summer, despite the fact that it’s Friday, despite the fact that tomorrow’s the weekend,’’ Paterson said. ‘‘The New York State Senate went to work, but they clocked in and clocked right back out.
