Rep. Justin Amash (R-MI) said Monday that he can’t think of any legislation proposed during his time in Congress that has been “more universally detested” than House Republicans’ bill to repeal and replace the Affordable Care Act.

“While I’ve been in Congress, I can’t recall a more universally detested piece of legislation than this GOP health care bill,” Amash tweeted.

Amash faced questions about the repeal from constituents at a town hall during the congressional recess in January. At that event, he advocated for a conditional state-by-state repeal of Obamacare to be activated only once state legislatures passed their own health care legislation to replace it.

In March, Amash said that House Republican leadership was trying to “ram” the repeal bill through Congress.

“The problem actually is that they’re not working with Democrats,” he said.

After the non-partisan Congressional Budget Office released a bruising report estimating that 24 million people would lose their insurance over the next 10 years under the repeal bill, Amash said it was “absolutely not true” that some Republicans had changed their votes on the legislation.

“It doesn’t repeal Obamacare,” he tweeted. “It remains a disaster.”
