House Minority Leader Nancy Pelosi said Friday that House Speaker Paul Ryan isn't brave enough to call up a bill to help the Dreamers, but said Democrats would keep pushing him.

"This fight is not over," she tweeted. "While I am disappointed @SpeakerRyan lacks the courage [to] lift the shadow of fear from these inspiring young ppl, I have hope."

The California Democrat and dozens of her colleagues voted against a short-term spending bill early Friday morning to protest the lack of any plan to hold a vote on immigration.

Republicans and Democrats have been negotiating for months to find a way to help Dreamers, or immigrants brought to the U.S. illegally as children. Republicans have also pushed for language that boosts border security, ends chain migration, and shuts down the U.S. diversity visa lottery.

But those demands have made Democrats balk.

In the Senate, Republicans have promised a vote next week on immigration, but it's not clear what bill will come up, and nothing is expected to pass without a reaching a political agreement first.
