No, you’re confusing two different mandates. Cooper asked him about the mandate that insurance companies offer insurance to people with pre-existing conditions.
This deceptive thread is trying to claim that Trump was referring to the mandate that people buy insurance—or get fined/taxed.
Trump supports the mandate requiring all individuals to buy health insurance, and under the Obamacare status quo within a highly restricted, over priced market.
Trump might clarify this tomorrow, i.e. it may not be what he meant to say, but it's what his words said.
COOPER: I got one question about it. If Obamacare’s Repealed and there’s no mandate for everybody to have insurance, what’s to - why would insurance company (sic) not have a pre-existing - insure somebody who has a pre-existing condition ...
TRUMP: Well I like the mandate. OK. So here’s where I’m a little bit different. I don’t want people dying on the streets and I say this all the time. And I say this - look, I did five speeches, maybe six speeches today. We had a lot of rallies. We had of thousands and thousands of people. We get big crowds.
Every time I talk about this I get standing ovations. The Republican people, they’re wonderful people. They don’t want people dying on the streets. Sometimes they’ll say Donald Trump wants single payer because there’s a group of people - as good as these plans are and by the way your insurance will go way down, you’ll have better plans, you’ll get your own doctor which Obama lied. Remember this ...
