‘Whistleblower’ who accused Bidens of corruption charged with arms trafficking

Gal Luft, who is a citizen of both the United States and Israel, is accused of paying a former adviser to Donald Trump on behalf of principals in China in 2016 without registering as a foreign agent.

I guess he didn't learn to whistle until after the Trump administration.

Is this the same one that they 'lost' and did they lose him because he was fleeing to avoid prosecution?

Accusations are one thing, evidence is another. It's not unreasonable to think that a corrupt person might have evidence of corruption in another person; it's also not unreasonable to think that a corrupt person might make unfounded accusations of corruption against another person.

Independently verifiable evidence, please.
