WASHINGTON -- The Republican Party filed a flurry of new lawsuits this week seeking reams of government documents related to Democratic presidential candidate Hillary Clinton's tenure as secretary of state.

The Republican National Committee filed four complaints on Monday in the U.S. District Court in Washington. The lawsuits stem from Freedom of Information Act requests the GOP filed last year. In court filings, the party says it has not received any documents in response to those requests.

"These lawsuits are intended to expedite the release of records covered under FOIA that will allow Americans to hold Hillary Clinton accountable," said RNC Chairman Reince Priebus.

The Republicans want all messages between 14 State Department officials and private email domains associated with Clinton, former President Bill Clinton, their daughter, Chelsea Clinton, and the Clinton Foundation. The GOP also wants communications between the State Department and officials at the U.S. Agency for International Development, which provides global humanitarian and development aid.

Another request targets records about training for State Department employees on the handling of classified information. Yet another seeks records pertaining to visitor logs or related records for Clinton's formal quarters or personal office while secretary of state and the State Department's Diplomatic Reception Room.

The latest batch of lawsuits joins a pair of complaints filed by the GOP earlier this month seeking emails and text messages from several of Clinton's key aides while she was secretary of state from 2009 to 2013.

All told, there are now at least 38 civil suits pending in federal court over access to Clinton's records, including one filed by The Associated Press.

On Tuesday, the Conservative legal advocacy group Judicial Watch filed a discovery motion seeking to question eight former State Department staffers under oath, including close Clinton confidantes Cheryl Mills and Huma Abedin. The judge overseeing the case indicated last month he was strongly considering allowing lawyers from the group to question Clinton's former aides.

The State Department has thus far released more than 52,000 pages of Clinton's work-related emails, but her private lawyers have withheld thousands more that they deemed to be personal communications unrelated to her job.

The FBI for months has investigated whether sensitive information that flowed through Clinton's email server was mishandled. The State Department has acknowledged that some emails included classified information, including at the top-secret level. The inspectors general at the State Department and for U.S. intelligence agencies are separately investigating whether rules or laws were broken.

Clinton has said her home-based email setup was a mistake, but that she never sent or received anything that was marked classified at the time.
