A measure to require law enforcement get a warrant if they want to use cellphone intercept technology in a criminal investigation is gaining momentum with a group of bipartisan lawmakers signing on in support.

Senate Bill 2343 and House Bill 4470, both introduced this month, would create the Citizen Privacy Protection Act. The House measure from Democratic Representative Ann Williams added several Republicans as co-sponsors this week. One of them, Republican Representative Tim Butler, says the technology is scary.

The American Civil Liberties Union of Illinois’ Ed Yohnka said Republicans signing on shows personal privacy is bigger than politics.
