Sen. Charles Grassley is investigating the matter, but his office says it has faced numerous obstacles due to the State Department’s refusal to hand over key information.

“Agencies should be transparent about their operations,” the Iowa Republican said in a statement to The Times.

“Basic information about a special category of employees who earn a government salary shouldn’t be a state secret. Disclosure of information builds accountability from the government to the taxpaying public. Agencies that lose sight of transparency also lose public trust.”

Abedin said she was thorough in keeping her work at the State Department separate from her private consulting in a letter she wrote in response to Grassley’s inquiry....

The consulting firm Abedin works for, Teneo, has also been scrutinized by the Times for blurring the line between charity and private profit. It was founded by former Bill Clinton aide and Coca Cola board member Douglas Band, who ran Teneo while overseeing one of the Clinton Foundation’s vast nonprofits, the Clinton Global Initiative.
