TALLAHASSEE, Fla. (AP) - A statistics professor is testifying that new political maps drawn by Florida legislators have a significant partisan bias.
    
Professor Jonathan Katz took the stand Tuesday during the trial to determine whether legislators broke the law when drawing up new maps for Congress.
    
A coalition of groups contends state legislators ignored a 2010 constitutional amendment that required them to draw up congressional districts that do not protect incumbents or members of a certain party.
    
Attorneys for the Legislature have denied any wrongdoing. If the court finds the current districts unconstitutional, it could force legislators to redraw them.
    
Katz, who was hired by the groups suing the Legislature, said it is did not seem "conceivable" that legislators could have drawn the current map without realizing it was skewed toward Republicans.
