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 weaponizing 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, but later returned to familiar themes: 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.

Punching back at the Department of Justice (DoJ)

The former president is currently duking it out with federal authorities over a cache of classified documents that the Federal Bureau of Investigation (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 documents.

Mr Trump has previously spun investigations and attacks against him as "witch hunts," and it was no different on Saturday.

He came out swinging, calling the FBI's search "the shameful raid and break-in on my home in Mar-a-Lago" a "travesty".

The former president has long built his appeal by casting himself and his supporters as political outsiders and persecuted figures.

Mr Trump linked his personal legal troubles to his supporters' political frustrations, claiming: "We are being assaulted… by the FBI and DOJ".

"It was not just my home that was raided… it was the hopes and dreams of every citizen who I've been fighting for since the moment I came down the golden escalator in 2015, wanting to represent the people," he said, drawing boos from the crowd.
