Sen. Frist has promised to finish work on the Homeland Security and Defense appropriations bills before Congress goes on recess. Will he deliver? Senate Majority Leader Bill Frist (R-Tenn.) promised lawmakers an aggressive work week Sept. 25, saying he is planning to use the next six days to finish critical appropriations bills, border security legislation, and measures dealing with President Bush's electronic surveillance program and military tribunals..... ...Both Frist and House Majority Leader John Boehner (R-Ohio) have said they may keep lawmakers in session until Sept. 30 to finish priority bills but then are determined to stick to their plans to adjourn. Legislation that is not finished by then, they said, will be held over until a post-election session to be held in November..... ....The GOP leader also said that he will be ready to bring to the floor conference agreements reached on the must-pass Department of Defense appropriations bill (H.R. 5631) and the spending bill for the Department of Homeland Security (H.R. 5441). But while conferees on the DOD bill already have announced a deal on that legislation, some issues raised by the Homeland Security bill have yet to be resolved, bringing into question when that measure will be ready for floor action. Conferees on the latter bill were planning to meet late Sept. 25 in an attempt to finish the legislation. "We absolutely must finish this week" the two FY 2007 appropriations bills, Frist said.
