Transcript for Trump breaks his silence on abortion issue
Overnight, president trump weighing in for the first time since Alabama and Missouri passed their abortion laws. ABC's David Wright. Reporter: The president has a series of late-night tweets last night including this one clarifying his views on abortion as you can see, for those who would like to know I'm strongly pro-life with these exceptions -- rape, incest and protecting the line of the mother, the same position, he says, taken by Ronald Reagan. The president went on to talk about judicial appointments and other issues. But there's a suggestion here that some of these new state laws may be more extreme than he would like. Missouri and Alabama have no exception for rape and incest. So the president taking credit here but also inserting some distance between him and some of these new state laws. These tweets grabbing attention. Up until now this is an issue that vice president pence has championed in this administration. That's right, pence has in the past called Donald Trump "The most pro-life president in American history." But it's pence really as an evangelical who has put this issue front and center, much more so than trump. Yesterday, vice president pence gave the commencement speech at Taylor university. In his home state of Indiana. The administration expects some of these new laws to land in court. And that's why the president has taken such care in his supreme court picks, both of them chosen very much with this issue in Eva. All right, David Wright at the white house, thank you. So much to talk about this morning. Let's bring in our chief anchor George Stephanopoulos, who will be hosting "This week" later this morning. Let's talk about the politics of this abortion story. The president is going out of his way to tout his pro-life on Twitter, how does this issue -- Abortion tends to work agait whichever party is more extreme on the issue. You saw with the president back in the state of union address was trying to focus on Democrats' support for late-term abortions. That's where they want the focus to be. These Alabama, Missouri laws, these fetal heartbeat laws flip that equation, because they don't have those exceptions for rape and incest. You also have this issue with abortion of be careful what you wish for. If indeed the Alabama law gets to the supreme court and the supreme court decides to overturn roe V. Wade, that's far more likely to energize democratic voters than Republican voters next fall. You're on your show this morning have three of sort of these lesser-known democratic contenders, how does anyone stand out in a field of 23 with Joe Biden at the top? That's the question. One thing we're committed to at ABC and "This week" to make sure that at least all the candidates are heard. Joe Biden has, I think people expected him to get in the race and be the front-runner. What's been a surprise, he's increased his lead over the last several weeks since he had that soft launch before the official launch yesterday. No front-runner gets to the nomination without a clear challenge, without going over a lot of hurdles. A million things can happen between now and the convention next summer. The questions for all those other candidates, how do you break out? What do you do to take him down? One thing we can say for sure it's going to be pretty interesting. And a reminder, George has a big show this morning. He'll speak with three democratic presidential candidates. Plus, Martha Raddatz is going to sit down with the former CIA director, general David Petraeus. To talk about the escalating tensions between the U.S. And Iran. That's all coming up on "This week" right here on ABC. George, thank you again.
