Republican Gov. Greg Abbott signed a bill into law that lets police ask during routine stops whether someone is in the country legally and threatens sheriffs and police chiefs with jail if they don't cooperate with federal immigration agents.
The timing of the signing caught Democratic lawmakers off guard.
Abbott signed the bill Sunday night during a Facebook Live event with no advance public warning.
He signed the measure four days after both chambers of the Legislature approved it. The new law goes into effect Sept. 1.
