In a letter to the FBI and Justice Department, Iowa Sen. Chuck Grassley tied President Biden to Hunter Biden's foreign business dealings.

The Senate Judiciary Committee is holding a hearing with Twitter's whistleblower, who claimed that China may have had access to Twitter data.

The now-former agent's 'blatant partisanship undermined the work and reputation of the FBI,' Sen. Chuck Grassley said.

'The American people deserve transparency and expect allegations of government corruption to be fully and immediately investigated.'

A former Twitter executive has become a whistleblower concerning Twitter's security infrastructure, which he claims is very unsafe.

'If these allegations are true and accurate, the Justice Department and FBI are - and have been - institutionally corrupted.'

Whistleblowers have also reached out to Republican Sen. Chuck Grassley of Iowa, the ranking member on the Senate Judiciary Committee.

GOP Sen. Chuck Grassley appeared on Fox News with Neil Cavuto on Saturday where he called out the double standards of the FBI.

Watch the mainstream media try to bury Grassley's allegations. But watch what a Republican-run House or Senate can do with them.

The story surrounding allegations against President Joe Biden's son keeps getting murkier. And GOP senators want answers.
