In an email to staff, Burke said:
"The work in every corner of this office - your work - has been significant and impressive. When I first came to this office a decade ago as a line AUSA (Assistant United States Attorney), I knew this was an excellent office and did important work."
Burke added, "My long tenure in public service has been intensely gratifying. It has also been intensely demanding. For me, it is the right time to move on to pursue other aspectsof my career and my life and allow the office to move ahead.
