WASHINGTON — Congressman Jason Altmire, D-4th, who hasn't yet decided whether to support landmark health care legislation, says he won't let politics or pressure determine which way he'll vote.

But in an interview this morning, Altmire, who represents part of southern Butler County, said he still has concerns about the costs involved in overhauling the medical delivery system.

He said on ABC's "Good Morning America" he still needs "to see better cost containment than was in previous versions of the bill." He said a critical issue is "changing the trajectory" of spiraling health costs across the country.

Asked if he felt an obligation to vote for it to support President Barack Obama, the congressman replied, "I'm not worried about the political implications of this."
