It says that the FBI sought a surveillance warrant against Carter Page one month before the 2016 election.
Page was a Trump foreign policy advisor, but he had recently left the campaign amid controversy over his Russian contacts.
The warrant was renewed three times, including after Trump took office.
This research became the notorious "dossier" that we've all heard so much about.
The memo is a Republican summary of secret documents that haven't been revealed. There may have been other key information involved.
Although the surveillance predates the appointment of Robert Mueller as special counsel, President Trump could use the memo in an attempt to undermine the investigation.
