A former aide to Trump adviser Roger Stone is trying to fight a grand jury subpoena issued as part of Robert Mueller’s investigation into Russian election meddling, arguing the probe is unconstitutional, according to his lawyer.

Andrew Miller, who did administrative work for Stone over the years, filed a sealed motion Thursday to have the subpoena thrown out, said Paul Kamenar, Miller’s lawyer. Miller is due to testify on Friday morning before a grand jury in Washington where he plans to refuse to answer questions, Kamenar said.
