Washington (CNN) — The Senate will take two key votes on Thursday on competing proposals aimed at ending the ongoing government shutdown -- one backed by Republicans and the other backed by Democrats and both likely to fail.

One of the votes will be on a proposal backed by Senate Majority Leader Mitch McConnell to fund President Donald Trump's border wall and reopen shuttered parts of the government. That legislation is in line with an offer the President proposed over the weekend offering temporary protections for some immigrants in exchange for $5.7 billion for a border wall -- and which Democrats swiftly rejected as they hold firm in insisting that the government should be reopened before lawmakers proceed to a debate on border security.

The other vote will be on House-passed legislation backed by Democrats to reopen the government without providing new funding for the wall.
