With the president expected to talk up his immigration plan, lawmakers have invited those affected by his policies to hear them firsthand. 

More than two dozen Dreamers — young immigrants brought to the U.S. illegally as children — will attend. Additionally, Marco Chavez, a Marine Corps veteran who was deported but recently allowed to return home, will attend as a guest of Rep. Nanette Diaz Barragán, D-Calif., while Jessica Fernanda Chillin, a Salvadoran-American with Temporary Protected Status, will attend as a guest of Rep. Don Beyer, D-Va. 

Also in the audience: A dozen women rising as part of the #MeToo movement, as well as guests who have experience with the opioids epidemic, the military, or LGBTQ issues. And Rep. Jim Bridenstine, R-Okla., will bring Bill Nye, the Science Guy.
