Trump supported the return of that decision to the States level. That's all. He's even said he'd VETO and Federal attempt to have a national law outlawing abortion. I think the vast majority of abortions are a disgusting form of retroactive birth control and those who use it as such are casually evil.
That said, I believe they have that choice and if they live in a state where enough of their neighbors agree with them, then so be it. Each individual choice will be judged in God's own timing. He is the judge, not me. Let the states decide.
