Senate Republicans on Tuesday were poised to block Democrats' landmark legislation on voting rights later in the day, but West pgslot Virginia Democrat Joe Manchin, who had been holding out, announced he would join his colleagues in a show of unity against the GOP move.

Senate Majority Leader Chuck Schumer said Manchin will vote to move forward with debate on the measure in exchange for a promise from Schumer that Manchin's proposed amendment with major changes would get a vote if debate opened.

Manchin released a statement saying while he does not support the original bill Democrats are pushing, he has "found common ground" on a possible new version.

Earlier, Manchin told ABC News Congressional Correspondent Rachel Scott, "We've just got to keep working. That's what we're here for."

The sweeping voting rights bill -- is a top priority for congressional Democrats and President Joe Biden -- but even with Manchin agreeing to vote to open debate, it appears certain Republicans will succeed in blocking the For the People Act from moving forward.

Despite Democrats not having the 60 votes necessary to overcome a GOP filibuster on the revised version of the S.1 elections reform bill, Schumer said Monday he's holding the vote, so even if it fails as expected, it will show Americans that congressional Republicans are. actively making it harder for people to vote.
