GRAND RAPIDS, MI - U.S. Rep. Justin Amash spent the evening Wednesday justifying his vote for a healthcare bill some of his constituents say is inhumane and immoral.

The congressman from Michigan's 3rd district voted yes earlier this month on what he called a "tweak" to the Affordable Care Act, drawing boos and insults from members of the crowd.

The group, made up of mostly Democrats and progressives, gathered on Wednesday, May 31 at Ottawa Hills High School for the Republican's most recent town hall meeting. Another is scheduled for set for 5:30 p.m. Thursday, June 1, at The Kool Family Community Center in Battle Creek.

In Grand Rapids, a Vietnam veteran warned he feared funding for his PTSD treatment would be dropped. A wife lamented her husband's battle with cancer amid rising medical costs.

"The bill is not as dramatic as some Democrats are making it seem," Amash said. "This bill is very similar (to ACA). It keeps in place the guaranteed issued provision and essential health benefits."

That statement spurred a booming "single payer, single payer" chant from the crowd that lasted nearly a minute long. Searching for common ground, Amash, a self-described Libertarian, suggested healthcare is too complicated an issue to make policy on a national scale.

"If people in Michigan want a single-payer system, they should be permitted to have that," Amash said. "But people in Oklahoma should not have to have the same healthcare as people in Vermont and so on."

Amash conceded he was not thrilled with the bill as drafted, but explained to voters in his district that "no perfect piece of legislation exists," and when presented with a bill on the floor he "has a decision to make."

Amash was also peppered with questions about America's role in global environmental sustainability, which was thrown into question earlier Wednesday with reports that President Donald Trump planned to withdraw the U.S. from the Paris climate agreement.

"I believe that should be debated in the Senate," Amash said, without stating whether he would support such action.

"I do believe humans effect the climate," Amash added. "The question is to what extent and then what do you do about it."
