The officials with whom Mueller has sought interviews who are traveling on the trip - like Hicks - will be interviewed when they return, the official said.
Hicks, 29, got her start working for Ivanka Trump before she moved up the ranks of Trump Organization and became a longstanding figure in the president's inner circle.
That same day, the Department of Justice (DOJ) disclosed that former Trump foreign policy adviser George Papadopoulos had already plead guilty to lying to the Federal Bureau of Investigation about his contact with Russian agents during the 2016 campaign. You can't go any lower.
As indictments were unsealed against former Trump campaign staff and special counsel Robert Mueller revealed Monday that at least one former Trump campaign adviser has pleaded guilty to federal charges, Trump's frustration with Kushner has grown exponentially, Vanity Fair reported.
According to two sources, Trump has complained to advisers about his legal team for letting the Mueller probe progress this far.
Speaking to Steve Bannon on Tuesday, Trump blamed Jared Kushner for his role in decisions, specifically the firings of Mike Flynn and James Comey, that led to Mueller's appointment, according to a source briefed on the call.
In another conversation with former adviser Roger Stone, Trump agreed with Stone's assessment that Kushner gave poor political advice. "Bannon recently told people he's not sure if Trump would survive such a vote", wrote Sherman. "I'm only saying publicly what everyone says behind the scenes at Fox News, in conservative media, and the Senate and Congress".
Influential Republicans are warning the White House to avoid such a direct attack.
Bannon reportedly believes Trump's hold on power is slipping in the wake of recent legislative failures.
Asked about another report that he's been "angry at everybody", Trump told the paper, "Actually, I'm not angry with anybody". A guilty plea by former Trump campaign adviser George Papadopoulos for making a false statement to the Federal Bureau of Investigation was also unsealed Monday. "But this pushes him aside".
