"Anchorage Republican Rep. Charisse Millett, last year's House GOP majority leader, and this year's minority leader, also described the travel expenses as lawmakers' own personal business."

Au contraire- it's the public's business when it's public money paying for legislative travel, especially the nonessential junkets described in the article. 

When Rep. Millett wants the travel to be legislators' personal business, she and her colleagues can pay for their own trips- out of their personal bank accounts. 

This is especially true when Leslie McGuire is allowed to spend thousands on a junket to Quebec to be added to her junkets list, including to Paris and Greenland.
