Wisconsin judge Ann Walsh Bradley says Justice David Prosser choked her

(CBS/WDJT/AP) MADISON, Wis. - Wisconsin Supreme Court justice Ann Walsh Bradley says Justice David Prosser choked her during an argument in her office earlier this month - a charge her colleague denies.

Bradley told the Milwaukee Journal Sentinel that Prosser put her in a chokehold after she demanded he leave her office.

"The facts are that I was demanding that he get out of my office and he put his hands around my neck in anger in a chokehold," Bradley told the newspaper.

Prosser issued a statement saying the allegations "will be proven false" once a "proper review of the matter and the facts surrounding it are made clear."

According to CBS affiliate WDJT, Wisconsin Public Radio and the Wisconsin Center for Investigative Journalism, quoting anonymous sources, have reported the altercation occurred before the Supreme Court's decision earlier this month upholding Gov. Scott Walker's bill to cut public employees' collective bargaining rights.
