Donald Trump has called President Joe Biden an "enemy of the state" at his first rally since the FBI searched his Florida resort for sensitive files.
Speaking to thousands of supporters in Wilkes-Barre, Pennsylvania, the ex-president accused Mr Biden of weaponising the FBI against him.
The raid was "one of the most shocking abuses of power by any administration in American history", Mr Trump claimed.
He was in the state to promote two Republican candidates.
Dr Mehmet Oz is running for the US Senate, and state Senator Doug Mastriano is in the race to become Pennsylvania's next governor.
Both spoke only briefly - as always, the rally on Saturday night was really about one person: the headliner.
Mr Trump, 76, spent the first part of his nearly two-hour speech criticising the FBI search early last month.
FBI agents conducting the search found dozens of empty folders marked as classified, and top secret files were recovered from his personal office.
Mr Trump, who is being investigated over his handling of classified records, denies wrongdoing.
Apart from the raid, the former president returned to familiar themes at the Pennsylvania rally: false claims that the 2020 election was stolen from him, attacks on rivals in the Democratic Party, and promises to "save our country".
Several times, he called for people who deal drugs to receive the death penalty.
Here are four key things you need to know about Donald Trump's rally.

The former president is currently involved in a legal tussle with federal authorities over a cache of classified documents that the FBI seized last month.
Government authorities say Mr Trump improperly took and stored White House documents, including some marked "top secret" at his Florida home - the Mar-a-Lago resort.
Federal prosecutors now say he may have obstructed the investigation into his possession of the document
