A bipartisan group of roughly 20 senators are working toward an agreement to reopen the government.

The bipartisan group isn't crafting separate legislation. Senators say the bulk of their talks were about how to get 60 votes for the bill to fund the government through Feb. 8, which would then be paired with a commitment that will satisfy Democrats on bringing up an immigration bill.
Collins said they are trying to reach a consensus on what would constitute a "fair process" on immigration, but declined to go into details, saying the talks are still "in flux."
