Senate Judiciary Committee Chairman Chuck Grassley on Wednesday pushed the Justice Department to release unredacted copies of text messages between FBI employees that displayed a bias against President Trump.

Specifically, the Iowa Republican drew attention to one text that says former President Barack Obama's "White House is running this."

“Congress, and the public, have a right to know how the Department spends taxpayer money,” Grassley said in a letter sent to Deputy Attorney General Rod Rosenstein calling for an uncensored release of messages between Peter Strzok and Lisa Page. Page resigned from the FBI earlier this month.

Strzok and Page, who previously served on special counsel Robert Mueller’s Russia investigation, found themselves at the center of a Senate investigation after their private text messages revealing an anti-Trump bias, among other tidbits of gossip from the department, were leaked. To aid in the investigation, the Justice Department allowed members of the Senate Judiciary Committee to view redacted versions of their conversations earlier this month.

One particular text, which was redacted, said "the White House is running this," referring to an investigation, and Grassley now wants to know which one.

Also at issue for the chairman were details of excessive spending, including a $70,000 conference table.

“I am unaware of any legitimate basis on which the cost of a conference table should be redacted,” Grassley wrote. “Embarrassment is not a good enough reason. The manner in which some redactions have been used casts doubt on whether the remaining redactions are necessary and defensible.”

Grassley set a June 6 deadline for DOJ to turn over the unredacted text messages or provide a legal basis for withholding the information from Congress.
