Washington – Justice Department Special Counsel Robert Mueller has issued grand jury subpoenas related to Donald Trump Jr.’s 2016 meeting with a Russian lawyer at Trump Tower, according to a person familiar with the matter.

The subpoena seeks both documents and testimony from people involved in the meeting, CNN has learned. That meeting has drawn scrutiny since an email exchange beforehand indicated the Russians offered damaging information on Hillary Clinton.

Mueller’s grand jury activity was first reported by The Wall Street Journal and Reuters.

Mueller’s team of investigators continue to look into whether President Donald Trump or any of his campaign associates colluded with Russia during the presidential contest.

The moves signal a new step in the investigation, which Trump has lambasted as a “witch hunt.” Trump has denied any collusion between his team and the Russians. US intelligence agencies have concluded that Russia attempted to sway the presidential contest in Trump’s favor.

Ty Cobb, special counsel to the President, said he wasn’t aware that Mueller had started using a new grand jury.

“Grand jury matters are typically secret,” Mr. Cobb said. “The White House favors anything that accelerates the conclusion of his work fairly… The White House is committed to fully cooperating with Mr. Mueller.”

Trump ignored shouted questions about Mueller as he departed the White House on Thursday afternoon.

Smiling and waving, Trump walked from the Oval Office to his Marine One helicopter on a sunny August afternoon. He was joined by son Eric Trump and daughter in law Lara Trump, as well as Jared Kushner and new chief of staff John Kelly.
A spokesman for Mueller’s office declined to comment on the reports.

Federal investigators have seized on Trump and his associates’ financial ties to Russia as among the most fertile avenues for moving their probe forward, people familiar with the investigation tell CNN.

The web of financial ties could offer a more concrete path toward potential prosecution than the broader and murkier questions of collusion in the 2016 campaign, these sources said.

In May, CNN reported that federal prosecutors had issued grand jury subpoenas to some associates of former national security adviser Michael Flynn as part of the ongoing probe into the Russian meddling.

Mueller took over that investigation in mid-May.

Those subpoenas were issued by the US Attorney’s office in Alexandria, Virginia, but the Wall Street Journal report indicated that Mueller would utilize a grand jury based in downtown Washington, near the offices where Mueller and his team work.

The question of Russian interference has hung over Trump’s presidency for months, even as the White House has sought to wall itself off from the matter. Trump has retained a team of lawyers to handle the growing legal swirl.
