The Republican push to repeal Obamacare is going on a fast track under a procedure that would make minority Democrats powerless to stop it, the first Republican congressman to endorse President-elect Donald Trump said Friday.

Republicans who now have unified control of Congress plan to move to repeal Obamacare during the first 100 days of the incoming Trump administration, said Rep. Chris Collins (R-NY).

They would do this under a budget procedure called 'reconciliation,' which requires a simple majority vote to approve tax and spending changes.

President-elect Donald Trump met with congressional leaders Thursday. The first congressman to back him says GOP leaders will use budget 'reconciliation' to repeal Obamacare – which would deny Democrats the chance to filibuster it

Democrats, who hold a strong minority in the Senate, would be unable to stop it unless they won some Republicans over to their side.

Collins said the first thing on Trump's plate was a repeal of Obama's executive actions. 'That can be done extraordinarily quickly,' he said.

'Repealing Obamacare I believe can be done in the first 100 days. You can repeal sections of it using reconciliation. I don’t think the Democrats are going to allow us if you will to just repeal it. They would filibuster that.'

Representative Chris Collins said Republicans would move to repeal Obamacare in Donald Trump's first 100 days, and Democrats won't get to filibuster the change

Collins spoke just a day after Trump held his first meetings separately with House speaker Paul Ryan of Wisconsin and Senate majority leader Mitch McConnell of Kentucky. Those two leaders, together with their committee chairman and budget leaders, would decide what kind of procedures get set up for repealing Obamcare.

Collins wasn't as clear about what Obamacare would get replaced with.

'The replacing piece, we have replacement ideas. We’re going to have to make sure we run that through the administration. That’s going to take longer. Lets face it it’ll be a transition. You don’t cut it off on a Tuesday and on Wednesday say here’s the new plan,' he said.

'Insurance companies have to put out their plans for 2018 in many cases by April. So we do have a timeline that we have to adhere to,' Collins continued. 'For the year of 2017, we’re not going to be pulling the rug out from anyone.'

Among those provisions Collins said would get repealed were a tax on medical devices that helps pay for the plan, a provision requiring employers to provide Obamacare to employees who work 30 hours or more, the mandate for employers to provide coverage, and a mandate for employees to obtain some type of coverage.

The provisions, if enacted, would gut President Obama's signature achievement. The plan has added about 20 million people to the rolls, in part through an expansion of Medicaid.

Some parts of the bill are extremely unpopular with Republicans and have been a rallying cry for years. In the weeks before the election, rate spikes were announced in numerous states where competition went down and insurance companies bailed out. Some state health exchanges were left with just a single provider.

After meeting with congressional leaders, Trump listed three priorities: 'We're going to move very strongly on immigration. We will move very strongly on health care. And we're looking at jobs. Big league jobs,' Trump said.

Collins acknowledged that some provisions might need to be dealt with other ways, including a part of Obamacare that prevents people from being denied coverage for having a preexisting condition.
