The Congressional Record is a unique source of public documentation. It started in 1873, documenting nearly all the major and minor policies being discussed and debated.
“CONFIRMATION” mentioning the U.S. Dept of State was published in the Senate section on pages S3157 on May 24, 2017.
The State Department is responsibly for international relations with a budget of more than $50 billion. Tenure at the State Dept. is increasingly tenuous and it's seen as an extension of the President's will, ambitions and flaws.
