President Obama is under fire from both liberals and conservatives over a new law that tightens who can travel to the U.S. under the visa-waiver program.

Civil rights advocates decry the GOP-authored law as heavy-handed. And now Republicans are unhappy with exemptions the Obama administration said it would allow.
