TOPEKA, Kan. — The Kansas Senate has advanced a bill aimed at furthering free-speech protections for college students.

But some critics worry that the measure given first-round approval Wednesday could have unintended consequences. Another, final vote is set for Thursday to determine whether the bill passes and goes to the House.

The bill would prevent state universities from establishing “free-speech zones” and disinviting offensive guest speakers. It also would ensure that university speech codes do not limit student speech.

Senators amended the bill to require universities to hold open meetings when discussing student fees.

Another proposed amendment that would have extended the bill’s free-speech protections to include faculty failed. Democratic Sen. Lynn Rogers of Wichita said the lack of protection for faculty members sends a message that they are “second-class citizens.”
