A conservative political advocacy group is inviting the public to a free forum about Medicaid this week in Tucson.

The event, hosted by the Arizona chapter of Americans for Prosperity, is scheduled for 6:30 to 9 p.m. Thursday at the Loft Cinema, 3233 E. Speedway.

Arizona state Sen. Steve Farley, D-Tucson and state Rep. Ethan Orr, R-Tucson, are among the scheduled speakers. Others include former state Sen. Frank Antenori, local physician Dr. Jane Orient and Arizona Board of Regents member Tyler Bowyer.

The state Legislature is scheduled to vote this session on whether to expand Medicaid, which is health insurance for lower income Americans.

In Arizona, the expansion would broaden the qualifications from 100 percent up to 133 percent of the federal poverty level, covering an additional 57,000 Arizonans. The state would then qualify for federal matching funds to restore coverage to about 240,000 childless adults and continue coverage for 50,000 others.

Officials with the state Medicaid program, known as the Arizona Health Care Cost Containment System, are scheduled to hold their own information forums about Medicaid expansion in the upcoming weeks. One of those forums is expected to be held in Tucson.
