"Trump's top economic and national security advisers refused to comment on the series of allegations that Trump's son-in-law and senior adviser Jared Kushner is facing regarding his contacts with Russian officials during a news briefing of Trump's maiden foreign trip".
During the meeting at Trump Tower in New York City, Kushner proposed using Russian diplomatic facilities for the discussions, apparently to make them more hard to monitor, according to The Washington Post, citing anonymous USA officials who were briefed on intelligence reports on intercepted Russian communications.

The committee is investigating Russian entanglements by figures in Trump's circle, including fired national security advisor Michael Flynn, who has been the target of multiple subpoenas.
Reuters has reported that Mr Kushner had at least three previously undisclosed contacts with Mr Kislyak previous year, including two phone calls between April and November.
In addition, Reuters reported that Kushner had at least three previously undisclosed contacts with Kislyak a year ago, including two phone calls between April and November.

The president has come under vast scrutiny at home for his recent firing of former Federal Bureau of Investigation director James Comey, who was investigating the Trump campaign for its alleged ties to the Russian government and its suspected involvement in influencing the 2016 presidential election.More news: F1 champion Alonso swigs milk at Indy, just not as winner
In what appeared to be a reference to the news the Federal Bureau of Investigation was looking into meetings held between Russian figures and Kushner, Trump wrote in a series of tweets: "It is my opinion that numerous leaks coming out of the White House are fabricated lies made up by the #FakeNews media". Kushner "suggested using Russian diplomatic facilities in the United States for the communications", the Post reported, in an apparent attempt to try to shield discussions during the transition from monitoring. Kushner's attorney, Jamie Gorelick, told Reuters that Kushner "has no recollection of the calls as described". But I do think there ought to be a review of his security clearance, and find out whether he was truthful and he was candid.
Kushner is under FBI scrutiny related to the investigation of the Russian meddling in the 2016 presidential elections.
The White House has previously confirmed that Kushner met with Kislyak at Trump Tower in December.
Trump also leaned on two administration officials with military experience to defend Kushner, who has become a significant person of interest in the FBI's investigation into whether the Trump campaign coordinated with Moscow in its efforts to sway the presidential election toward Trump.

Separately, there were at least 18 undisclosed calls and emails between Trump associates and Kremlin-linked people in the seven months before the November 8 presidential election, including six calls with Kislyak, sources told Reuters earlier this month.
"I think he's going to continue to hold the line that he has, which is that it's fake news until somebody comes up with some evidence of some actual wrongdoing", Hemingway said. He added: "It allows you to communicate in a discreet manner".
