Bloomberg:

AT&T Inc. (T), with its T-Mobile USA takeover facing regulatory opposition, is preparing the biggest remedy proposal yet to the Justice Department to salvage the $39 billion deal, according to a person familiar with the plan.The company is considering an offer to divest a significantly larger portion of assets than it had initially expected, said the person, who declined to be identified because the plan isn’t public. Though the exact size of the disposals hasn’t been determined, they could be as much as 40 percent of T-Mobile USA’s assets, the person said.

AT&T has billions riding on the outcome either way. They’re motivated to make it happen no matter the cost.
