(BEGIN VIDEOTAPE)

UNIDENTIFIED MALE: Starting right now on THIS WEEK WITH GEORGE STEPHANOPOULOS, Trump's terrible week -- the billionaire frontrunner down big in Wisconsin, after seeing his top adviser arrested, sparking a firestorm over abortion and getting slammed on his foreign policy.

(BEGIN VIDEO CLIP)

DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: I'm not sure which is worse, dealing with the party people or dealing with the press.

(END VIDEO CLIP)

UNIDENTIFIED MALE: Now, is Trump more vulnerable than ever? and could a Wisconsin loss make a convention clash inevitable?

The Republican Party chair and Trump rival John Kasich are both here.

Plus, fed up and feuding...

(BEGIN VIDEO CLIP)

HILLARY CLINTON (D), PRESIDENTIAL CANDIDATE: And I'm also a Democrat. That's kind of important.

SEN. BERNIE SANDERS (I-VT), DEMOCRATIC PRESIDENTIAL CANDIDATE: Secretary Clinton owes us an apology.

UNIDENTIFIED MALE: As Bernie Sanders gains in the polls, the Democratic fight for the nomination gets heated.

Bernie Sanders joins us live.

From ABC News, it's THIS WEEK.

Here now, chief anchor George Stephanopoulos.

(END VIDEOTAPE)

GEORGE STEPHANOPOULOS, ABC HOST: Was this week the tipping point for Donald Trump?

Imagine any other candidate enduring the week he had. Imagine one dealing with it the way he did.

It began with a battery charge for campaign manager, Corey Lewandowski, after surveillance video proved he grabbed reporter Michelle Fields at a Trump rally last month.

Now, most candidates would discuss the staffer. Not Trump, he blamed the reporter.

(BEGIN VIDEO CLIP)

TRUMP: She didn't almost fall to the ground. She -- he -- he got in her way. And by the way, she was grabbing me.

Am I supposed to press charges against her?

(END VIDEO CLIP)

STEPHANOPOULOS: Then there was Trump's trouble with abortion.

(BEGIN VIDEO CLIP)

CHRIS MATTHEWS, MSNBC HOST, "HARDBALL": Do you believe in punishment for abortion, yes or no, as a principle?

TRUMP: And the answer is that there has to be some form of punishment.

MATTHEWS: For the woman?

TRUMP: Yes, there has to be some form.

(END VIDEO CLIP)

STEPHANOPOULOS: After the predictable firestorm...

(BEGIN VIDEO CLIP)

SEN. TED CRUZ (R-TX), PRESIDENTIAL CANDIDATE: Being pro-life is not only about defending the unborn children, it's also about defending the mothers.

CLINTON: Donald Trump is showing us exactly who he is and we should believe him.

(END VIDEO CLIP)

STEPHANOPOULOS: Trump forced to backtrack.

(BEGIN VIDEO CLIP)

TRUMP: The laws are set now on abortion and that's the way they're going to remain.

(END VIDEO CLIP)

STEPHANOPOULOS: Another clarification followed. Only the late night comics seemed to be happy with how it ended up.

(BEGIN VIDEO CLIP)

UNIDENTIFIED MALE: So at this point, Donald Trump has to be pro-choice because he's made all of the choices.

(LAUGHTER)

(END VIDEO CLIP)

STEPHANOPOULOS: And on foreign policy, Trump shattered more than half a century of security policy by hinting at how he would use nuclear weapons and suggesting Japan and South Korea should considering building nuclear arsenals of their own.

(BEGIN VIDEO CLIP)

GOV. JOHN KASICH (R-OH), PRESIDENTIAL CANDIDATE: You wonder about his hand or his thumb getting any close to the critical button that presidents are in charge of.

(END VIDEO CLIP)

STEPHANOPOULOS: President Obama weighed in, too.
