Senator-elect Scott Brown is demanding that he be sworn in immediately rather than next week as planned.

In a letter Wednesday to Massachusetts Gov. Deval Patrick, Brown's attorney says the newly elected lawmaker does not want to miss any votes in the Senate.

Brown wants the Jan. 19 election results to be certified by 11 a.m., Thursday Feb. 4., so that he can be sworn in earlier than his original target date of Feb. 11.

A spokesman for Senate Majority Leader Harry Reid said officials will aim to meet his request.

Earlier Wednesday, official copies of the election results were delivered to the Governor's Council. Gov. Patrick will sign Brown's election certificate, as required, during a ceremony at 9:30 a.m. Thursday.

Shortly after Brown's win, President Obama and Sen. Reid assured him no votes would be taken on health care until he is sworn in.

Still, the senator-elect says there are Senate votes he may want to participate in, though he didn't specify which ones.

Brown defeated Democrat Martha Coakley to fill the seat held by the late Sen. Ted Kennedy for decades. The victory gives the GOP 41 Senate votes-- enough to sustain a filibuster against Democrats.
