Trump has 'total confidence' in son-in-law Kushner

Current and former Trump administration officials told The Times they had come to think the meeting in December could have been when Kushner tried to reach out to the Russians.

The allegations against Mr Kushner dominated an end-of-trip briefing for reporters in Taormina, Italy, where General H R McMaster, the President's national security adviser, and economic adviser Gary Cohn, declined to comment on Mr Kushner.

On Twitter, the president said "Russian officials must be laughing at the USA - and how a lame excuse for why the Dems lost the election - has taken over the fake news". Kushner would speak "when the time is right", he said. "I'd let him speak for himself when the time is right".

In interviews Sunday, Homeland Security Secretary John Kelly said he did not know if the reports are true.

The White House has been shaken by an explosive Washington Post report on the eve of his return that said Kushner had met with the Russian ambassador prior to Trump's inauguration and proposed a secret communications link to the Kremlin.

CNN reported on Thursday that the Federal Bureau of Investigation was looking into Kushner's many roles on both Trump's transition team and in the White House.

Mr Trump, who participated in the annual Memorial Day ceremony at Arlington Ceremony on Monday, is said to be considering a shake-up of the White House administration, with a possible sidelining of press secretary Sean Spicer and other key officials expected in the coming days.

"#FakeNews is the enemy!" he continued. Fox News has learned Cohen has now been issued a subpoena.

Mr Trump's tweets came as the media reported that the White House was preparing to establish a "war room" to combat mounting questions about ties between Russian Federation and his presidential campaign.

The investigation into Russia's influence in last year's presidential election has now spread to include Donald Trump's personal attorney.

In recent weeks, the president's relationship with his son-in-law, the most stable partnership in an often unstable White House, is showing obvious signs of strain.

The meeting also was attended by Michael Flynn, Trump's first national security adviser.

Trump plans to bring in new aides to the White House, adding experienced political professionals including a former campaign manager, according to administration officials and persons close to the president.

Corker also separately praised President Donald Trump on his first official global trip since taking office, saying in a news release that it was "executed to near perfection".

Trump has frequently dismissed his campaign's connection with Moscow as an excuse by Democrats to explain his win over Democrat Hillary Clinton.
