An FBI agent who raided Paul Manafort's home last year testified that the FBI knocked three times before entering his condo in Washington's Northern Virginia suburbs.

FBI agent Matthew Mikuska said that he and other agents gathered outside Manafort's door, then knocked on three separate occasions and announced that the FBI was there to execute a search warrant.

When nobody answered the door, the agents used a key that they already had and entered the condo, Mikuska said. When they walked in, they saw Manafort standing nearby.

The raid occurred shortly after 6 a.m., Mikuska said.

Some news reports shortly after the July 2017 search suggested that it was a "no-knock raid." Mikuska's testimony on Wednesday disputed these reports.

Prosecutors already said in earlier court filings that the raid was not a "no-knock raid."
