This is how a grand jury helps the Trump-Russia investigation

Earlier on Thursday, Aug. 3, the Wall Street Journal reported that special counsel Robert Mueller has convened a grand jury for his Russian Federation investigation.

The subpoena [related to the Donald Trump Jr. meeting] seeks both documents and testimony from people involved in the meeting, CNN has learned.

Trump believes that there have been supporters of Hillary Clinton hired by Mueller, and that the special investigator is good friends with the previous investigator, Comey.

The work of the grand jury marks a new phase in Mueller's investigation.

The Wall Street Journal was first to report that the legal team of special counsel Robert Mueller has started up a grand jury.

White House spokeswoman Sarah Huckabee Sanders said the president was not likely the subject of the investigation, AFP reported.

It is also one of only two Arab governments that have signed a peace treaty with Israel and established full diplomatic relations. Israeli Prime Minister Benjamin Netanyahu spoke by phone to Israel's ambassador in Jordan, the ministry said.

He added: "The White House is committed to fully cooperating with Mr. Mueller".

"A back-end judicial review process to prevent unmerited removals of special counsels not only helps to ensure their investigatory independence, but also reaffirms our nation's system of check and balances", Tillis said in a statement. "So again, you know, grand juries are supposed to be secret proceedings, evidently, you know, not so secret right now".

As the Journal notes, a separate grand jury in Alexandria, VA, had already been convened prior to Mueller's appointment to look into former National Security Adviser Mike Flynn's work on behalf of foreign governments.

It remains unclear how long Mueller's investigation into allegations of collusion between Russian Federation and the Trump campaign will last. Earlier on Thursday, the U.S. Senate introduced two bills with the express aim to limit the ability of Trump to sack the special prosecutor the way he had sacked James Comey the FBI Director when he started investigating deeply into the connection of Trump's team with Russian Federation.

"It was the middle of the afternoon, and he just picked up the phone to say how innocent I was", Trump said. Sources described an investigation that has widened to focus on possible financial crimes, some unconnected to the 2016 elections, alongside the ongoing scrutiny of possible illegal coordination with Russian spy agencies and alleged attempts by President Donald Trump and others to obstruct the FBI investigation.
