(MSC News)--A complaint is filed following the removal of news media by the Kansas Senate Wednesday.

That move, made during the Legislature’s last day in session, came as protesters in the Senate gallery sang and chanted in support of state Medicaid expansion.

The Associated Press reports the Senate halted its work to clear the gallery floor, with Capital Police requiring reporters to leave the chamber temporarily.

The complaint is filed on behalf of the Kansas Sunshine Coalition for Open Government, the Kansas Press Association, the Kansas Association of Broadcasters, and the Kansas Institute for Government Transparency.

The letter, outlining the formal complaint, is addressed to Kansas Attorney General Derek Schmidt, and signed by Ron Keefover, the President of the Kansas Sunshine Coalition for Open Government

The complaint calls the action taken by Senate President Susan Wagle “unprecedented,” and says the removal of the news media is “clearly an unconstitutional breach of both the Kansas Constitution and the U.S. Constitution's right to liberty of the press,” as well as to the Senate’s own rules.

The complaint urges an investigation by the Attorney General’s Office in order to reach a “speedy resolution,” including a preliminary restraint which the letter says “may be achieved in a consent order.”

Wagle’s office, following the removal of the media and protesters, Tweeted that it was done for safety reasons. Her chief of staff, Harrison Hems, told reporters they were giving demonstrators "an audience" by shooting pictures and recording video, making it harder to restore order.

Wagle later said her office wasn't singling out reporters, only trying to clear the floor and end the demonstration.
