The future of US deputy attorney general Rod Rosenstein remained in the balance on Monday night amid reports that the senior US justice official was considering resigning.
After a morning of feverish speculation, the White House announced that Mr Rosenstein and US president Donald Trump would meet in Washington on Thursday, when the president is due to return from attending the United Nations General Assembly in New York.
Asked about the future of the man who set up the Russia investigation, Mr Trump replied: "We'll see what happens.
“We want to have transparency, we want to have openness, and I look forward to meeting with Rod.”
Mr Trump has consistently railed against the Mueller investigation into Russian interference in the 2016 election, accusing US justice and intelligence officials of being biased against him.
Huge implications
As the justice official overseeing the Mueller probe, Mr Rosenstein’s departure of could have huge implications for the inquiry.
Although technically responsibility for the investigation would likely fall to the solicitor general, a successor to Mr Rosenstein would have the power to curtail the probe.
Last week the New York Times reported that Mr Rosenstein had suggested secretly recording Mr Trump and had encouraged cabinet members to consider invoking the 25th amendment to the constitution to remove Mr Trump as president. Mr Rosenstein has denied the reports.

The second-in-command at the justice department attended meetings at the White House on Monday morning, prompting reports that he was resigning.
But the White House said that, at the request of Mr Rosenstein, he had an “extended conversation” with Mr Trump by phone about “recent news reports”, and they had agreed to meet on Thursday.
Stand-off
The prospect of a high-profile departure from the administration emerged amid a deepening stand-off over the nomination of supreme court nominee Brett Kavanaugh, after a second allegation of sexual misconduct surfaced.
Republicans are seeking to confirm their pick for the court before November’s midterm elections, but Mr Kavanaugh’s nomination has been thrown into uncertainty over sexual misconduct allegations.

While last year Mr Trump lambasted North Korea in his speech, this year he is expected to turn his focus to Iran. The US pulled out of the 2015 Iran nuclear deal in May, in defiance of other international signatories to the agreement, including EU countries.
Iran's president Hassan Rouhani will address the general assembly later on Tuesday.
