That was 19 September 2022. Less than a year later, on 11 August, Mr Garland announced that Mr Weiss would receive special counsel status.
But the Republican senator from Texas is now calling the appointment of the same person he was urgently recommending a “wildly inappropriate” pick to lead the investigation.
“This appointment is camouflage and it’s cover-up. I think it’s disgraceful,” he told Fox News on 13 August.
Mr Weiss, who has served as the US Attorney for Delaware since 2018, has led federal investigations into President Joe Biden’s son since 2019. Last month, Hunter Biden was reportedly prepared to enter a plea deal following charges stemming from unpaid taxes and a federal application for a firearm.
That deal appeared to fall apart, and Hunter Biden pleaded not guilty to two of the charges after a federal judge questioned whether the deal would prohibit other potential prosecutions.
IRS whistleblowers speaking to Republican members of Congress who are eager to prosecute the president’s son have claimed that it was necessary that Mr Weiss be designated special counsel powers because he could not pursue prosecutions in other jurisdictions outside of Delaware, as the US attorney for that state.
Whistleblowers also testified that US Department of Justice officials had prevented Mr Weiss from seeking felony tax evasion charges in California and Washington DC.
Mr Cruz is now accusing Mr Weiss of either being an “active participant” in covering up “criminality” and obstructing justice by “protecting” the president, or “he was just complicit.”
“He was so weak that he couldn’t stop the partisans in main justice from turning it into a political effort to protect Joe Biden,” Mr Cruz said.
But in their letter to Mr Garland last year, Mr Cruz and 32 other senators said it is “important” that Mr Weiss receive special counsel status to “allow him to investigate an appropriate scope of potentially criminal conduct, avoid the appearance of impropriety, and provide additional assurances to the American people that the Hunter Biden is free from political influence.”
Mr Cruz now accuses Mr Weiss of spending “the last five years covering it up”.
The senator has also been requesting information from Mr Weiss this month, sending a letter with a list of questions surrounding whistleblower testimony, none of which accuse Mr Weiss of wrongdoing.
The Independent has requested comment from his office.
His apparent about-face follows other objections from GOP officials who had also previously called for Mr Weiss to step in as special counsel.
Tennessee Senator Marsha Blackburn, another senator who signed last year’s letter, claimed that Mr Garland only appointed Mr Weiss because “he knows Weiss will protect Hunter Biden.”
In her appearance on Fox News, she called Mr Weiss “a collaborator”.
“The sweetheart deal that he had cooked up for Hunter Biden, now they’re going to give him a sweetheart deal with a special counsel and run out the plot,” she said. “Merrick Garland, he owes the American people better than to do something like this.”
South Carolina Senator Lindsey Graham – another signatory – told NewsNation that the appointment “poured gasoline on a political fire.” He told Fox News that he believes Mr Weiss has been “compromised” after a “sweetheart” plea deal fell apart.
And Iowa Senator Chuck Grassley – who acknowledged signing the letter during an appearance on Fox News – said that Mr Weiss has “pulled punches” and “didn’t investigate as he should’ve.”
