Rep. Jerrold Nadler, a New York Democrat, said Wednesday that Attorney General William Barr “appears to be waging a media campaign” on behalf of President Donald Trump.

Nadler warned that if the report is heavily redacted, the committee will issue subpoenas “in short order.”

He says the attorney general’s decision to hold a Thursday morning news conference, before releasing a redacted version of Robert Mueller’s report to Congress, will “again result in the report being presented through his own words.”

He warns that if the report is heavily redacted, the committee will issue subpoenas “in short order.”

Nadler says he will “probably find it useful” to call Mueller and members of his team to testify after reading the version of the report Barr releases.
