ANNOUNCER: From ABC News, THIS WEEK WITH GEORGE STEPHANOPOULOS starts now.

(END VIDEOTAPE)

STEPHANOPOULOS: Two breaking stories this morning and we begin with that tense scene in the House overnight.

(BEGIN VIDEO CLIP)

REP. STENY HOYER (D), MD.: A shutdown is not a tactic. It is a failure for this country.

REP. DANA ROHRABACHER (R), CALIF.: Please accept the compromise and keep the government open.

(END VIDEO CLIP)

STEPHANOPOULOS: When it all wrapped up, House Republicans passed a bill that would keep the house open only if ObamaCare was delayed for a year. That is a non-starter for Democrats. So let's get more on what happens next from our chief White House correspondent Jon Karl.

And, Jon, hard to say how long it will last, but this makes some kind of shutdown late tomorrow all but certain.

JONATHAN KARL, ABC NEWS CHIEF WHITE HOUSE CORRESPONDENT: Oh, that's right, George, positions have hardened. Time is running out. I would now put the chances of a government shutdown at 99.9 percent. It was after midnight at a raucous session last night that the House did what they did.

The bill, what it would actually do, it would fund the government until December; it would delay ObamaCare for one year and it would repeal a tax on medical devices that's part of the health care law. They also separately passed a provision that would fund the troops regardless of a government shutdown.

The White House response was swift, George, Jay Carney saying "Today Republicans in the House of Representatives moved to shut down the government."

And it's hard to disagree with that because the Senate absolutely will not pass what just passed in the House. And, George, the Senate doesn't get back into session until 2 o'clock tomorrow afternoon. That is 10 hours before the government shuts down.

STEPHANOPOULOS: So they sent their bill right back to the House.

What happens next?

KARL: But what I'm hearing this morning from Republicans is they will still attempt to put provisions in there dealing with the health care law and send it back to the Senate. This ping-pong back and forth will go no signs of compromise on either side.
