On this weekend's "Sunday Square Off":

-Our "Left/Right" debate on the big news of the week: the Florida high school massacre, the DACA stalemate in Congress and, here in Arizona, a new move to give Republicans control of drawing up congressional maps.

I'm joined by attorney Roy Herrera, a former Democratic congressional aide and federal prosecutor, and Barrett Marson, a Republican political consultant.

-You may not know what Bitcoin is, but legislators want to let you pay your state taxes with it. Republican State Rep. Jeff Weninger of Chandler explains.

-Democrat Brianna Westbrook, Arizona's first transgender candidate for Congress, tells us how she'd pay for her progressive agenda. Westbrook's running in the Eighth Congressional District primary Feb. 27.

-The president of the Arizona Board for Charter Schools tells me why she was powerless to shut down a failing Goodyear school last summer. The school went belly up last month, leaving parents and teachers scrambling in the middle of the school year.

"Sunday Square Off" airs at 8 a.m. Sundays, after NBC's "Meet the Press."
