U.S. Reps. Keith Ellison and Betty McCollum are among the House Democrats who plan to fast today in support of activists pushing the House to take up comprehensive immigration reform.

The lawmakers took over for three activists who had camped on the National Mall without food for three weeks to raise awareness and make the case for reform.

The U.S. Senate passed an immigration bill this year, but work on legislation has stalled in the Republican-led House.

"It is imperative that the House of Representatives follow the bipartisan lead of the United States Senate and pass comprehensive immigration reform legislation before the end of this year," McCollum said in a statement.

"Immigration reform is one of the most pressing issues facing our country today and it has the support of the business community, faith leaders, law enforcement, labor, and families throughout Minnesota."
