PORTLAND, Maine (AP) - U.S. Sen. Susan Collins of Maine says Democrats made a mistake in ramming the Affordable Care Act through without a single Republican vote seven years ago. The Republican says she doesn't want her party to do the same thing.

Collins and fellow Republican Sens. John McCain of Arizona and Lisa Murkowski of Alaska voted "no" early Friday on the GOP's latest effort to repeal former President Barack Obama's health care reform law. Their votes killed the legislation.

Collins is urging both parties to work together through the committee process going forward.

Independent U.S. Sen. Angus King of Maine is praising the three Republicans for showing courage. He says in a statement that "it's easy to stand up to your opponents, but it's hard to stand up to your friends."
