Some in Arizona would like to ban Academics from commenting on the political process:
The bill, whose chief sponsor is the Republican majority leader in the Senate, would ban professors at public colleges and universities, while working, from:
Endorsing, supporting or opposing any candidate for local, state or national office.
Endorsing, supporting or opposing any pending legislation, regulation or rule under consideration by local, state or federal agencies.
Endorsing, supporting or opposing any litigation in any court.
Advocating “one side of a social, political, or cultural issue that is a matter of partisan controversy.”
Hindering military recruiting on campus or endorsing the activities of those who do.
