WASHINGTON -- As undocumented immigrants prepare to apply for President Barack Obama's new deportation relief programs, they're also facing a barrage of concerning news. House Republicans voted to end the policies. Senate Republicans are aiming to do the same. Twenty-six states sued the federal government, hoping to block Obama's programs from going into effect, and the House is considering filing a suit as well. It's enough to make some undocumented immigrants nervous -- and some advocates think that's the intention.
