Providence Mayor Angel Taveras, Treasurer Gina Raimondo, former Obama administration official Clay Pell and contractor Todd Giroux are scheduled to participate in a live edition of Rhode Island Public Radio's "Political Roundtable" on Tuesday evening.

Taveras, Raimondo and Pell met last month in their first televised debate. They worked to draw differences among themselves despite agreeing on many big issues, including the need to jumpstart the troubled economy.

Giroux ran for governor as an independent in 2010 and got 882 votes.

The two Republican candidates, Cranston Mayor Allan Fung and Moderate Party founder Ken Block, will participate in a public radio round table next Tuesday.
