On Monday, the US Department of Justice announced charges including secret political lobbying and arms trafficking against an American-Israeli analyst who had previously accused US President Joe Biden's son of corruption.

A statement from the Department of Justice said that federal prosecutors in New York charged Gal Loft, who heads a think tank outside the US capital, with engaging in "multiple and serious criminal schemes."

Luft had previously alleged that President Biden's family was involved in corruption, prompting Republican politicians to view the charges against him as an attempt to intimidate a key witness.

According to the prosecution, Luft "violated US foreign agent registration laws in an effort to promote Chinese policies by working through a former high-ranking US government official."

In addition, Luft "was a broker in dangerous arms deals and Iranian oil (...) and told numerous lies to law enforcement agencies to cover up his crimes," according to the statement.

The prosecution stated that Loft was arrested in February in Cyprus on US charges, before he managed to escape after being released on bail pending extradition procedures. He is still at large and the Ministry of Justice is requesting information on his whereabouts.

In a video released by the New York Post last week, Luft said that in 2019 he provided evidence to US Justice Department and FBI officials regarding what he alleged were the Biden family's financial dealings with the CFFC.

Republican Senator Ron Johnson accused the US government of a cover-up.

Johnson told Fox News recently that Luft "has a wealth of information. But they never followed up on it," adding, "Instead they arrested him in Cyprus to silence him."

And as Biden intensified his efforts to be re-elected as president for a second term in 2024, Republicans in Congress accused his family in May of collecting more than $ 10 million from dealings with Chinese and Romanian companies, despite the weak evidence they presented.

These accusations are part of an old campaign to target Hunter Biden, the president's son from his first marriage.

Republicans accuse Hunter Biden of exploiting his father's influence when he was deputy to Barack Obama in order to strike deals in many countries.
