A lawyer at the United States’ most elite firm has broken his silence to criticise Donald Trump’s recent Tweetstorm.

George Conway III is a partner at Wachtell Lipton Rosen & Katz, widely regarded as America’s most exclusive and prestigious firm.

He is also a Trump supporter and is married to Kellyanne Conway, a White House senior adviser close to the President.

In the wake of the attack on London last weekend, Trump let off a series of Tweets, including some on his proposed ‘travel ban’, an immigration order which would restrict people from certain countries entering the US.

Conway, who has had a Twitter account since 2012 but had not Tweeted since December 2015, broke his silence to point out that Trump’s outburst would make it harder for the Office of the Solicitor General to argue the case for the immigration order in the Supreme Court.

He went on to add a series of Tweets expressing his support for the President, but adding that “Tweets on legal matters seriously undermine [the Administration’s] agenda” and the President himself.

Conway was considered for various positions within the Trump administration, including Solicitor General. However, he recently withdrew from consideration to lead the Civil Division of the Department of Justice, citing family reasons.
