House Judiciary Committee Chairman Jerry Nadler, D-N.Y., vowed to bring Attorney General William Barr before Congress to testify after Barr released a summary of special counsel Robert Mueller’s report, which found no collusion between President Trump and Russia.

Earlier Sunday, Nadler said he would appeal to the Supreme Court to get the whole report if needed. The four-page summary written by Barr said that there wasn’t a conspiracy between Trump and Russia, although it did not determine whether Trump obstructed justice.

“In light of the very concerning discrepancies and final decision making at the Justice Department following the Special Counsel report, where Mueller did not exonerate the President, we will be calling Attorney General Barr in to testify before @HouseJudiciary in the near future,” Nadler wrote as part of long string of tweets Sunday afternoon.

“There must be full transparency in what Special Counsel Mueller uncovered to not exonerate the President from wrongdoing. DOJ owes the public more than just a brief synopsis and decision not to go any further in their work," he said.

“Special Counsel Mueller worked for 22 months to determine the extent to which President Trump obstructed justice. Attorney General Barr took 2 days to tell the American people that while the President is not exonerated, there will be no action by DOJ,” Nadler also wrote.

Speaking at a press conference Sunday evening in New York, Nadler said he would subpoena Barr to get him to testify if needed.

"I would hope that it would not be necessary to use subpoena power to get the attorney general to appear before the committee," Nadler said. "We also want to see the full report and if necessary, we'll use subpoena power to get that, too."

Nadler and other Democratic leaders have said they want Barr and Mueller to testify. The House voted 420-0 this month to release the report to the public.
