President Donald Trump on Wednesday praised the latest attempt from Senate Republicans to repeal and replace the Affordable Care Act, yet chided his party for a delayed and tedious process that has plagued his administration in its early months.

Trump commended the Graham-Cassidy-Heller-Johnson (GCHJ) legislation, saying it offered the best chance to repeal the "disastrous" law known as Obamacare.

"I think there is tremendous support for it," Trump said at the United Nations. "I actually think it is much better than the previous shot, which was very sadly let down. Again, you've been hearing about repeal and replace for seven years. They have a chance."

The statement followed tweets from the president Wednesday morning calling the new plan "GREAT!" Trump also blasted Sen. Rand Paul for his opposition to the bill.

Later Wednesday, Trump complained about the process by which Republicans have attempted to repeal and replace the law. He noted that the GOP promised to repeal the law for seven years — yet for the first eight months of the Trump administration have been unable to do so.

"I thought that when I won I would go to the Oval Office, sit down at my desk, and there would be a healthcare bill on my desk — to be honest," Trump said. "It hasn't worked out that way, and I think a lot of Republicans are embarrassed by it."

Experts say the latest Republican legislation would increase state flexibility for healthcare — but at the expense of billions of dollars in funding, weaker protections for people with preexisting conditions, and a significantly larger number of uninsured Americans.

Senate Majority Leader Mitch McConnell said Wednesday that he is planning to bring the bill to the floor next week.
