Senate Republicans announced plans to vote next week on their latest bid to scuttle Obamacare even as a popular comedian who has become part of the U.S. health care debate denounced the bill and former President Barack Obama on Wednesday warned of ¡°real human suffering.¡±

President Donald Trump endorsed the legislation on Twitter. But Republicans and the White House were on the defensive after Jimmy Kimmel used his late-night TV show to blast the proposal and call Republican Sen. Bill Cassidy, one of its two sponsors, a liar.

¡°This guy, Bill Cassidy, just lied right to my face,¡± Kimmel said on his show on Tuesday night, referring to the senator who since May had touted a ¡°Jimmy Kimmel test¡± of standards any Obamacare replacement would need to possess.
