Judiciary Committee move comes after Justice Department misses deadline for unredacted Mueller report.

The House Judiciary Committee said it would vote Wednesday on whether to hold Attorney General William Barr in contempt, escalating a dispute with the Trump administration after Mr. Barr missed a congressional deadline to turn over an unredacted version of special counsel Robert Mueller’s report.

The Justice Department says it is legally barred from turning over the full report because it contains information obtained by using a grand jury, which is by law secret. It has also maintained that Congress has no right to demand raw evidence gathered in a criminal probe. Courts have ordered grand jury material to be released in previous investigations involving presidents, as in during Watergate and the Clinton impeachment. The committee has urged Mr. Barr to request a court unseal the Mueller report—a step he hasn’t taken. The department has also said it has already accommodated public interest in the report by releasing a redacted version to the public and making a less redacted version available to senior congressional leaders.
