The American Bar Association (ABA) has sued the administration of US President, Donald Trump, seeking an order that would prevent the White House from pursuing what it called a campaign of intimidation against major law firms.

The lawsuit, filed on Monday in a federal court in Washington, DC, alleged that the administration violated the United States Constitution by issuing a series of executive orders targeting law firms over their past clients and employees.

According to the complaint, those executive orders were used to ?to coerce lawyers and law firms to abandon clients, causes, and policy positions the President does not like?.

Dozens of executive agencies and US officials are named in the suit, including Attorney General Pam Bondi, Director of the Federal Bureau of Investigation Kash Patel and Secretary of State Marco Rubio.

In a statement, the ABA ? the country?s largest voluntary association for lawyers ? called Trump?s attacks on law firms ?uniquely destructive?.

?Without skilled lawyers to bring and argue cases, the judiciary cannot function as a meaningful check on the executive branch,? the association wrote.

Four law firms have separately sued the administration over President Trump?s orders, which stripped their lawyers of security clearances and restricted their access to government officials and federal contracting work.

Four different judges in Washington have sided with the firms and temporarily or permanently barred Trump?s orders against them. One of the firms that sued and won a preliminary victory, Susman Godfrey, is representing the ABA in Monday?s lawsuit.

White House spokesperson Harrison Fields responded to Monday?s lawsuit with a statement calling it ?clearly frivolous?.

He added that the ABA has no power over the president?s discretion to award government contracts and security clearances to law firms.

?The Administration looks forward to ultimate victory on this issue,? Fields said.

Despite Trump?s court losses, nine law firms have struck deals with the president, pledging to offer nearly $1bn in free legal services to stave off similar executive orders.

Monday?s lawsuit escalates a clash between the ABA and the Trump administration, which has cut some government funding to the group and has moved to restrict its role in vetting federal judicial nominees.

In March, Bondi ? the chief law enforcement officer in the US ? warned the group that it could lose its role in accrediting law schools unless it cancels a requirement related to student diversity. (Al Jazeera)
