'We will protect Medicare and Social Security' -Trump
"We will protect Medicare and Social Security. We will always and very strongly protect patients with pre-existing conditions. And that is a pledge from the entire Republican Party," Trump said.
Republicans opposed Obamacare as a whole, but the provision to cover pre-existing conditions has proven very popular with Americans.
Trump's administration asked the Supreme Court in June to invalidate the Obamacare law.
Democrats took over the House of Representatives after the 2018 midterm congressional elections in large part by emphasizing their commitment to preserve the Affordable Care Act.
Republicans have sought to scrap Obamacare and Trump has promised an alternative but never produced one.
