Kellyanne Conway’s husband schools Trump while appearing to defend FBI raid of Michael Cohen's office

The husband of a senior White House adviser appears to have called out the US president on Twitter, after Donald Trump expressed outrage at FBI raids on the law office and hotel suite of his personal lawyer.

George Conway, the partner of White House counsellor Kellyanne Conway, appeared to troll Mr Trump after the president tweeted that “attorney-client privilege is dead” after Michael Cohen’s offices were raided.

Mr Conway has been a regular critic of Mr Trump on Twitter, and retweeted the message from the president on Tuesday morning with a link to a page on the Justice Department website that seemed to directly contradict him.

It outlined why Mr Cohen's offices were not protected from a Monday no-knock FBI raid by attorney-client privilege.

"There are occasions when effective law enforcement may require the issuance of a search warrant for the premises of an attorney who is a subject of an investigation, and who also is or may be engaged in the practice of law on behalf of clients," the Justice Department's website reads.

"In order to avoid impinging on valid attorney-client relationships, prosecutors are expected to take the least intrusive approach consistent with vigorous and effective law enforcement when evidence is sought from an attorney actively engaged in the practice of law."

The Justice Department manual for US attorneys outlines how to conduct a search without infringing on attorney-client privileges.

The website then lists a number of guidelines the government are required to follow when attaining evidence under such circumstances such as getting permission from either the attorney general or assistant attorney general.

Mr Conway, who married the Trump advisor in 2001, also retweeted an image of an old Washington Post headline which reads "Nixon sees 'witch-hunt,' insiders say."

Mr Conway’s position on the president is at direct loggerheads with his wife who formerly ran Trump's campaign and has made frequent TV appearances to defend the billionaire's actions and comments.

In March, Mr Conway deleted a number of previous tweets which criticised the president in the wake of speculation Ms Conway could be named as White House communications director.

Last June, Mr Conway insisted he "very, very strongly" supports the president but argued his tweets "seriously undermine" his administration's agenda.

"Just to be clear, and in response to inquiries, I still VERY, VERY STRONGLY support POTUS, his Admin, policies, the executive order ... and of course, my wonderful wife," Mr Conway tweeted.

Mr Conway chiefly retweets items others have posted and adds just sporadic commentary. After Mr Trump signed a $1.3 trillion spending bill he retweeted the growing national debt total on two separate occasions.

The Conways' relationship began after he asked friend and right-wing commentator Ann Coulter to arrange an introduction with the Republican pollster he watched from afar on TV. He pushed back his own career with a leading New York law firm to relocate their family to Washington so she would be able to follow hers.

But in Washington Ms Conway’s own career has been beset with gaffes and she has become known for coining the now infamous phrase “alternative facts”.

Her blunders include referring in a TV interview to a terrorist attack that never happened - terming it the “Bowling Green massacre” - suggesting Barack Obama could have spied on Mr Trump using a microwave, and claiming the national security adviser Michael Flynn had the “full confidence” of Mr Trump hours before he was fired.
