Adult-film star Stormy Daniels' lawsuit against US President Donald Trump's personal lawyer, Michael Cohen, will be put on pause for 90 days, the federal judge has ordered.
The judge said Cohen's constitutional rights could be endangered if the lawsuit proceeds while he is under criminal investigation.
Cohen has admitted paying $US130,000 to Daniels, whose real name is Stephanie Clifford, to secure her silence about having sex with Trump, which he denies.
Cohen said the payment was legal, and Daniels has sued to end her nondisclosure agreement.
Daniels' lawyer Michael Avenatti promptly pledged to fight the stay, writing on Twitter he would file an immediate appeal to the US Court of Appeals for the Ninth Circuit in California, which could ultimately lead the Supreme Court to have to weigh in.
Cohen said earlier this week he would invoke the fifth amendment and refuse to answer questions in the lawsuit after the FBI raided his home, office and hotel room two weeks ago.
The Fifth Amendment to the US Constitution states that no individual can be "compelled in any criminal case to be a witness against himself."
Daniels had countered that the lawsuit should proceed, with Cohen invoking the amendment only for specific questions that might lead to self-incrimination.
But Otero wrote that approach could lead to Cohen not answering any questions, rendering a deposition useless.
The stay is warranted "to determine that the scope and context of the FBI investigation and potential criminal proceedings will not substantially interfere with this action," Otero wrote.
