An informant familiar with Mar-a-Lago and the whereabouts of classified documents former President Donald Trump potentially stored there tipped off the FBI before it executed a search warrant on Monday, according to reports from Newsweek and The Wall Street Journal .

The National Archives retrieved 15 boxes of documents from the Palm Beach, Florida, residence in February before asking the Justice Department to investigate Trumps potential crimes in violating the Presidential Records Act by storing government materials at his home.

On Monday, the FBI searched the residence and private club , reportedly as part of an investigation into whether Trump mishandled classified documents.

The raid didnt transpire without inside help.

Two senior government officials, who requested to stay anonymous but had information about the search, told Newsweek that one individual guided authorities to documents at Mar-a-Lago and that the raid was set to occur when Trump was out of town to avoid a galvanizing photo-op.

The Wall Street Journal corroborated those claims, speaking with anonymous sources who said the informant knew the location of these classified documents and that Trump stored many more at Mar-a-Lago than the 15 boxes retrieved in February.

The former president made it a felony to mishandle classified documents in 2018.
