A blistering order from President Donald Trump accused the powerhouse firm of "obvious partisan representations." The firm calls it a presidential effort to silence opponents.

Jenner & Block claims the order keeping them from federal contracts and federal buildings is an unconstitutional abuse of power against the lawyers, their clients and the legal system.

A U.S. judge on Friday said he is inclined to temporarily block Republican President Donald Trump's administration from enforcing his order targeting prominent Washington law firm WilmerHale over its work for Democrats and its connection to a special counsel who investigated him.

Trump said the firm — where former special counsel Robert Mueller was once a partner — was “yet another law firm that has abandoned the profession’s highest ideals and abused its pro bono practice to engage in activities that undermine justice and the interests of the United States”.

U.S. ethics disclosures made public on Friday from some of President Donald Trump’s top legal nominees, including the lawyer to lead the U.S. attorney’s office in Manhattan, offered a glimpse at compensation at some of the country's most prestigious law firms.

Jenner & Block has sued the US government over Donald Trump’s executive order that targeted the law firm for its ties to the prosecutor who investigated the president’s alleged collusion with Russia during his first term.

President Trump has targeted big law firms that he claims have “weaponized” the legal system. On Friday, Jenner & Block and WilmerHale fought back in court.
