Rep. Luis Gutierrez (D-Ill.) is wrapping up his 21-city tour backing immigration reform Saturday in Chicago — President Barack Obama’s hometown — with another call for him to follow through on the issue.

Gutierrez, who Obama cited in a recent press conference for his work on the issue, has repeatedly argued for bringing the immigration issue to the forefront.

“Though we have only just passed the first 100 days of the Obama administration, it is the 11th hour for our immigrant community, and there is no time to waste,— he said in a statement. “On Saturday, Chicago’s families will come forward to honor their mothers in the most important way — by demanding family unity.—

The “Family Unity Tour— has featured 25 Members, including Speaker Nancy Pelosi (D-Calif.). Obama has committed to start to work on the issue, but has not committed to push for a vote this year on a comprehensive bill.
