Senior appellate litigator Michael Dreeben told a federal judge on Tuesday that he and his co-counsel “face the press of other work” and would like a deadline extension this week in response to a request to unseal court documents in Paul Manafort’s now-wrapped criminal case.

Dreeben is working with Adam Jed, a more junior appellate lawyer on Mueller’s team, to respond to the request from The Washington Post. The newspaper first approached the federal court in Washington on March 7 asking for the unsealing of Manafort documents related to his breach of plea proceedings. Its request came the same day Manafort learned his first of two prison sentences, which together totaled about 7.5 years.

On Tuesday, Dreeben and Jed asked federal Judge Amy Berman Jackson, who oversaw Manafort’s foreign lobbying-related case and his plea, to move the deadline for their response to the Post from this Friday to April 1.
