PORTLAND — Former White House Chief of Staff Erskine Bowles will be in Portland this weekend to talk about the national debt and the effort he led to reduce the deficit.

Bowles will take part in a town hall event Sunday at the University of Southern Maine organized by the Angus King for Senate campaign. King, the independent former governor, invited Bowles to participate in the campaign event and has said he agrees with the overall approach of the report.

“While I may not agree on all the details, I think the overall approach … makes a great deal of sense: cut spending in an intelligent way, simplify the tax code, cut tax rates and eliminate most loopholes to generate additional revenue,” King wrote in a statement posted on his website.

Bowles, a Democrat who served former President Bill Clinton, was co-chair of the bipartisan commission along with former Republican Sen. Alan Simpson of Wyoming. The commission was appointed by President Barack Obama and it released an outline last year of ways to reduce the national debt by $4 trillion by 2020, mostly through spending cuts.

The forum will be held in USM’s Hannaford Hall from 12:30 to 2 p.m. It is open to the public but requires registration. It also will be streamed online at www.Angus2012.com.
