Three women - including one who said her only crime was laughing - were convicted Wednesday on charges of disrupting the confirmation hearing of U.S. Attorney General Jeff Sessions.

The women were part of activist group Code Pink and were protesting Sessions' Jan. 10 Senate confirmation hearing. Two of the women, Tighe Barry and Lenny Bianchi, appeared at the Washington, D.C. hearing dressed as Ku Klux Klan members. They were acquitted on a count of disorderly conduct but convicted on two separate charges of parading or demonstrating, the New York Times reported.

A third woman, Desiree Fairooz of Virginia, was found guilty of disorderly conduct and parading or demonstrating on Capitol grounds.

Each faces up to 12 months in prison.

Fairooz, who wore a pink Lady Liberty costume to the Sessions' hearings, maintained all she did during the testimony was laugh. The 61-year-old woman previously declined to accept a plea bargain from prosecutors, opting to move ahead with the case.

The three women had pleaded not guilty of all charges.

Fairooz explained her laughter was in response to a comment by Alabama Senator Richard Shelby, who said Sessions had a record of "treating all Americans equally under the law is clear and well-documented."

"I just couldn't hold it," Fairooz reportedly said during the trial. "It was spontaneous. It was an immediate rejection of what I considered an outright lie or pure ignorance."

Prosecutors contended the women planned to "impede, disrupt, and disturb the orderly conduct" of the hearing.
