A lawyer for President Donald Trump says he has no reason to believe the president is under federal investigation amid a media report that Special Counsel Robert Mueller is using a grand jury as part of his probe.

Attorney John Dowd said in a statement to The Associated Press on Thursday that he had no information suggesting that the president himself is under investigation.

The Wall Street Journal reported Thursday that Mueller was using a grand jury in Washington.

A grand jury is a common vehicle for government investigators to subpoena witnesses and records, though it doesn't suggest any charges are near.

A grand jury in Virginia has been used to gather information on Michael Flynn, Trump's former national security adviser.

Ty Cobb, special counsel to the president, also says he had no knowledge of a grand jury.

He says such matters are typically secret, and the White House "favors anything that accelerates the conclusion of his work fairly."
