Jared Kushner and Russia’s ambassador to Washington allegedly discussed setting up a secret communications channel to cloak contacts between Moscow and Donald Trump’s White House transition team, it was reported.

Ambassador Sergei Kislyak told his superiors in Moscow that he and Mr Kushner discussed ways to shield their pre-inauguration discussions from monitoring, the Washington Post said, citing US officials briefed on intelligence reports.

Mr Trump’s son-in-law made the proposal at a meeting in early December at Mr Trump Tower in New York, weeks before Mr Trump was sworn in, according to intercepts of Russian communications that were reviewed by the US officials, the paper said.

Michael Flynn, Mr Trump’s first national security adviser, also allegedly attended the meeting.

The report will likely put Mr Kushner, who is now a senior White House adviser, under heightened scrutiny in the investigations into the Trump campaign’s ties to Russia.

Earlier this week it was reported that the FBI was investigating his contacts with Russian officials.

In a separate development, the Washington Post also reported that the Senate intelligence committee, which is investigating Russian interference in the 2016 presidential race, has asked Trump’s political organization to produce all documents, emails and phone records dating from his campaign’s launch in June 2015.

It would be the first time the Senate’s bipartisan investigation has made such a request to Trump’s official campaign organization.

The White House made no immediate response to requests for comment on either report.

Jared Kushner is under scrutiny in the FBI's Trump-Russia investigation. In other news, water is wet. — Maxine Waters (@MaxineWaters) May 26, 2017 If true, this is treasonous activity, whether borne of malice or naïveté, or both. https://t.co/Wm4rk3bgtC — Evan McMullin (@Evan_McMullin) May 26, 2017

Mr Trump is concluding his first foreign trip as president this week. He has repeatedly denied any collusion with Russia.

Two other outlets published related scoops yesterday.

The first from the New York Times said that Oleg Deripaska, a Russian oligarch once close to Paul Manafort, Mr Trump’s former campaign manager, offered to cooperate with congressional committees investigating Russian meddling in return for immunity.

Lawmakers rejected his conditions, the Times reported.

And Reuters, citing seven current and former US officials, reported that Mr Kushner had at least three contacts with Mr Kislyak during and after the presidential campaign that were previously undisclosed.

Those contacts allegedly included two phone calls between April and November 2016.

In response to the Reuters report, Mr Kushner’s attorney, Jamie Gorelick, said Mr Kushner did not remember any calls with Kislyak between April and November.

“Mr Kushner participated in thousands of calls in this time period. He has no recollection of the calls as described. We have asked [REUTERS ]for the dates of such alleged calls so we may look into it and respond, but we have not received such information.”

The cascade of news showed that the multiple Russia inquiries are advancing and that leaks continue to spout from the government, giving administration officials no respite even as they trot the globe.

The White House disclosed Mr Kushner’s meeting with Mr Kislyak in March, four months after it happened, and played down its importance. But the Washington Post reported that the FBI now considers the encounter, plus another meeting Mr Kushner had with a Russian banker, to be of investigative interest.

Mr Kushner, who is married to the president’s daughter, Ivanka, has said he will co-operate with any investigation.

Current and former US intelligence officials were astonished that he would have requested a secret back channel, calling it “naive” or “crazy” given the FBI’s close tabs on Russian officials in the US, the Post reported.

Evan McMullin, an independent candidate in the 2016 presidential race, said the report raised the stakes for Mr Kushner.

“If true, this is treasonous activity, whether borne of malice or naïveté, or both,” he tweeted.

Maxine Waters, the Democratic congressional firebrand, expressed little surprise at the latest allegation.

“Jared Kushner is under scrutiny in the FBI’s Trump-Russia investigation. In other news, water is wet.”
