Audrey Strauss, a former top in-house lawyer at Alcoa and senior litigation partner at Fried Frank Harris Shriver & Jacobson in New York, was named on Friday the second-in-command at the Manhattan U.S. attorney’s office, succeeding Robert Khuzami.

The shuffling puts Strauss in line to lead the office’s investigation into President Donald Trump’s inner circle, a probe that poses a broad threat to Trump and his administration. The Manhattan prosecution office led the case against Trump’s former personal lawyer and “fixer,” Michael Cohen, who is soon heading to prison for crimes tied to his close connections to Trump.
