WASHINGTON — Special counsel Robert Mueller’s team raised the prospect of issuing a grand jury subpoena to compel President Donald Trump to testify as part of the Russia probe, the president’s former attorney said Tuesday.

Attorney John Dowd told The Associated Press that Mueller’s team broached the subject in March during a meeting with Trump’s legal team while they were negotiating the terms of a possible interview with the president.

The meeting marked the first time the special counsel’s office raised the possibility of compelling Trump to testify as part of the ongoing investigation. Mueller is probing not only Russian election interference and possible coordination with Trump associates but possible obstruction of justice by Trump.

Dowd’s comments come more than a month after he resigned from the legal team, and they provide a view into the Trump legal team’s interactions with the special counsel.
