A bipartisan think tank is pushing back against immigration advocates who want President Obama to use his executive authority to expand a program to defer the deportations of undocumented immigrants.

The nonprofit Bipartisan Policy Center said Thursday that doing so would undermine the public's faith in immigration laws and undercut the legislative process in Congress, where lawmakers are debating a broader immigration overhaul.

In a statement, the think tank's immigration task force said that using "the president’s executive authority to sidestep Congress would undermine that trust and confirm the fears of those who believe the government is not serious about upholding all elements of reform, particularly the implementation of stronger border security measures and workplace screening of undocumented individuals."
