The House Judiciary Committee had already approved issuing subpoenas for former White House counsel Don McGahn and a few others. Now that Robert Mueller's report has been released, the committee has taken the next step, summoning McGahn to testify May 21. The panel, run by Democrats, also wants certain documents turned over by May 7. The action seems to indicate, CNN reports, that the committee plans to look further into the revelations about the actions of the president and his administration detailed in Mueller's report.
The report "outlines substantial evidence that President Trump engaged in obstruction and other abuses," said Jerrold Nadler, the committee's chairman, per the Washington Post. He said McGahn was "a critical witness to many of the allege instances of obstruction of justice and other misconduct." He's the first former White House employee to be subpoenaed by Congress since the report was released; the committee issued a subpoena for the full Mueller report, without redactions, and other evidence last week. The committee's top Republican, Doug Collins, said McGahn has testified enough, per CNN; he was interviewed by Mueller's team for more than 30 hours. (McGahn may have saved Trump by ignoring his order, one analyst says.)
