Joe Biden Addresses Rudy Giuliani's Home and Office FBI Raid

President Joe Biden has said he did not know about the raid of Rudy Giuliani's premises before it took place and vowed not to interfere in any investigation into the personal lawyer of ex-President, Donald Trump.

In an interview with NBC's show Today, Biden was asked whether he was aware ahead of time about the FBI raid of the home and office of Giuliani, which forms part of a probe into the former New York City mayor's dealings with Ukraine.

"I give you my word I was not," he said. "I made a pledge I would not interfere in any way, order or try to stop any investigation" involving the Justice Department.

"I learnt about that last night when the rest of the world learnt about it," he added.

When host Craig Melvin asked Biden if he had been briefed on any other investigations into Giuliani, he replied: "No, and I am not asking to be briefed. That's the Justice Department's independent judgement.

"This last administration politicized the Justice Department so badly," Biden said, adding, "the Justice Department is the people's lawyer, not the president's lawyer."

Giuliani tried to find incriminating evidence about Biden and his son, Hunter, in Ukraine before the 2020 election. Biden won the election and he and his son have denied any wrongdoing.

Meanwhile, Giuliani's attorney Robert Costello said his client denies any wrongdoing in his Ukraine dealings and has called the searches in which electronic devices were seized, "legal thuggery."

In the wide-ranging interview, Biden also defended his administration's immigration record when asked about the fate of hundreds of migrant children separated from their parents under former President Trump's family separation policy.

"We don't know yet where those kids are. We're trying like hell to figure out what happened," he said, urging those in Central America "do not send your kids, period."

Biden was also asked to respond to the GOP rebuttal by Senator Tim Scott of his joint address to Congress this week in which the South Carolina lawmaker said that America was "not a racist country."

"I don't think the American people are racist," Biden told NBC, "but I think after 400 years, African Americans have been left in a position where they are so far behind the eight ball in terms of education and health, in terms of opportunity.

"I don't think America is racist, but I think the overhang from all of the Jim Crow and before that, slavery, have had a cost and we have to deal with it."
