A group of Senate Democrats who are considered potential contenders for the party's 2020 White House nomination are coming out against a two-year budget deal.

Each of the lawmakers pointed to the lack of a resolution for the Deferred Action for Childhood Arrivals (DACA) program as a reason for their opposition.

Congress has until March 5 to pass a fix for the program or hundreds of thousands of immigrants brought into the country illegally as children will be at risk of being deported.

A continuing resolution (CR), included as part of the budget deal, would keep the government open until March 23 , weeks past the immigration deadline.

Warren touted the agreement as making "real progress on .... middle-class priorities I've spent months pushing for," while doing nothing "to the ongoing crisis facing 800,000 Dreamers."

"Republican leadership has refused to do the morally right thing by protecting the young people who know only this country as their home," Gillibrand added in her statement.

A spokesman for Harris also confirmed that the California Democrat would oppose the budget deal, which will also increase the debt ceiling.
