Suzan Johnson Cook, the State Department’s ambassador-at-large for international religious freedom, will announce this week that she is resigning after 17 months on the job, according to two sources familiar with her office.

President Obama nominated the former Baptist minister to serve as his top adviser on protecting religious freedom around the world. When confirmed by the Senate in April 2011, she became the first woman and the first African-American in the position, which had been held by two people before her.

Obama had been criticized for taking too much time after his own swearing-in to nominate a religious freedom ambassador, a position created by the International Religious Freedom Act of 1998.
