A Republican senator has made a request to obtain 'all email communications' between former President Barack Obama and Hillary Clinton while she was secretary of state.

Senator Ron Johnson of Wisconsin, chairman of the Committee on Homeland Security and Governmental Affairs, sent the request to the National Archives in a letter on Thursday.

Though no emails to or from Obama from Clinton's private email server have been made public, Johnson cited a text message from former FBI lawyer Lisa Page to ousted agent Peter Strzok hinting at the existence of such communications.

'Jim – I have the POTUS – HRC emails [FBI Director James Comey] requested at end of briefing yesterday. I hesitate to leave them, please let me know a convenient time to drop them off,' the June 8, 2016 text message reads.

In the letter, Johnson said that he had previously requested that the Justice Department produce any emails between Clinton and Obama sent while she was in 'the territory of a technologically sophisticated adversary.'

Republicans have long contended that Clinton's use of a private email server while secretary of state could have exposed her communications to interception by foreign adversaries.

The DOJ rebuffed Johnson's request, however, stating that the 'referenced email is not a Department document and contains equities of other executive branch entities.'

Johnson's new request to the National Archives was made under the auspices of the Presidential Records Act. The senator gave the archives a deadline of November 14 to produce the emails.

It comes just a week after an internal State Department probe into Clinton's use of private email found violations by 38 current and former department officials, some of whom may face disciplinary action.

The investigation, launched more than three years ago, determined that those 38 people were 'culpable' in 91 cases of sending classified information that ended up in Clinton's personal email, according to a letter sent to Republican Senator Chuck Grassley.

The investigation covered 33,000 emails that Clinton turned over for review after her use of the private email account became public. The department said it found a total of 588 violations involving information then or now deemed to be classified but could not assign fault in 497 cases.

Clinton spokesman Nick Merrill said in a tweet Saturday: 'For the umpteenth time the email story is put to bed w/ a clear recognition it was a pointless crusade that took away from so many other issues we should have been discussing in '16.'

By seeking Clinton's emails with Obama, Senate Republicans may be looking to revive interest in the private email scandal, just as the House impeachment inquiry into President Donald Trump reaches new intensity.

On the same day as Johnson's letter, House Democrats voted to formalize the impeachment inquiry into Trump, setting up the next stage of dramatic and ultra-partisan televised hearings in the probe.
