Republican Sen. Susan Collins signaled a willingness to work with Democrats on healthcare legislation, adding momentum to President Barack Obama's push for a bill despite a move by Republican leaders to slow down the debate. Collins's fellow senator from Maine, Olympia Snowe, became the first Republican lawmaker to back a Democrat-led health bill with a "yes" vote in the Finance Committee. Collins said she would "work with members on both sides of the aisle" to craft bipartisan legislation.
