(CNSNews.com) - With the government shutdown over, President Trump on Tuesday is turning to other breaking news: Reports that five months' worth of text messages exchanged by two anti-Trump, pro-Clinton FBI agents have gone missing.

Trump tweeted on Tuesday morning: "In one of the biggest stories in a long time, the FBI says it is now missing five months worth of lovers Strzok-Page texts, perhaps 50,000, all in prime time. Wow!”

Agent Peter Strzok was involved in both the Hillary Clinton email investigation and the Russia-Trump investigation before his text messages to and from Lisa Page came to light.

Strzok, who was having an affair with Page, was removed from the Russia probe and reassigned to the FBI's human resources department last summer, after Special Counsel Robert Mueller learned about the politically biased text messages exchanged by Strzok and Page.

Fox News reported on Monday that Strzok and Page exchanged more than 50,000 texts, but five months' worth of texts -- spanning the presidential transition and the beginning of Robert Mueller's Russia probe -- have disappeared.

“After reviewing the voluminous records on the FBI’s servers, which included over 50,000 texts, the Inspector General discovered the FBI’s system failed to retain text messages for approximately 5 months between December 14, 2017 to May 17, 2017,” Attorney General Jeff Sessions said in a statement to Fox News.

“We will leave no stone unturned to confirm with certainty why these text messages are not now available to be produced and will use every technology available to determine whether the missing messages are recoverable from another source,” Sessions said. “If we are successful, we will update the congressional committees immediately.”

This is just the latest jaw-dropper regarding senior officials at the FBI:

Some Republican lawmakers, including Rep. Jim Jordan of Ohio, believe FBI officials used the salacious "Trump dossier," paid for by the Clinton campaign and the Democratic National Committee, to get warrants to spy on Americans associated with Donald Trump's campaign.

Jordan believes it was Strzok who took the opposition-research dossier to the FISA court to launch the Russia investigation.

Then there are questions about the way the investigation into Hillary Clinton's emails was conducted.

Texts exchanged between Strzok and Page indicate that then-Attorney General Loretta Lynch knew Clinton would be exonerated by then-FBI Director James Comey, two months before Comey completed his investigation and even before the FBI interviewed Clinton (but not under oath).
