President Joe Biden issued historic preemptive pardons for former NIAID Director Anthony Fauci, House Jan. 6 committee members, and others on Monday, granting them broad immunity just hours before President-elect Trump’s White House return.

Biden stunned many when he issued the blanket pardons before Trump’s swearing-in at the U.S. Capitol on Monday.

“Our nation relies on dedicated, selfless public servants every day. They are the lifeblood of our democracy. Yet alarmingly, public servants have been subjected to ongoing threats and intimidation for faithfully discharging their duties,” Biden wrote.

“In certain cases, some have even been threatened with criminal prosecutions, including General Mark A. Milley, Dr. Anthony S. Fauci, and the members and staff of the Select Committee to Investigate the January 6th Attack on the United States Capitol. These public servants have served our nation with honor and distinction and do not deserve to be the targets of unjustified and politically motivated prosecutions,” he added.

“General Milley served our nation for more than 40 years, serving in multiple command and leadership posts and deploying to some of the most dangerous parts of the world to protect and defend democracy. As Chairman of the Joint Chiefs of Staff, he guided our Armed Forces through complex global security threats and strengthened our existing alliances while forging new ones,” Biden said.

“For more than half a century. Dr. Fauci served our country. He saved countless lives by managing the government’s response to pressing health crises, including HIV/AIDS, as well as the Ebola and Zika viruses. During his tenure as my Chief Medical Advisor, he helped the country tackle a once-in-a-century pandemic. The United States is safer and healthier because of him,” Biden added.

“On January 6, 2021, American democracy was tested when a mob of insurrectionists attacked the Capitol in an attempt to overturn a fair and free election by force and violence. In light of the significance of that day. Congress established the bipartisan Select Committee to Investigate the January 6th Attack on the United States Capitol to investigate and report upon the facts, circumstances, and causes of the insurrection. The Select Committee fulfilled this mission with integrity and a commitment to discovering the truth. Rather than accept accountability, those who perpetrated the January 6th attack have taken every opportunity to undermine and intimidate those who participated in the Select Committee in an attempt to rewrite history, erase the stain of January 6th for partisan gain, and seek revenge, including by threatening criminal prosecutions,” he continued.

Biden concluded, “I believe in the rule of law, and I am optimistic that the strength of our legal institutions will ultimately prevail over politics. But these are exceptional circumstances, and I cannot in good conscience do nothing. Baseless and politically motivated investigations wreak havoc on the lives, safety, and financial security of targeted individuals and their families. Even when individuals have done nothing wrong—and in fact have done the right thing—and will ultimately be exonerated, the mere fact of being investigated or prosecuted can irreparably damage reputations and finances.”

After more than 50 years in politics and with low approval ratings, President Biden is leaving Washington and his official public life behind.

Biden has spent the last few weeks drafting executive orders that will be difficult for President Donald Trump to revoke after withdrawing from the political limelight after resigning as the Democratic presidential nominee for 2024.

Biden is departing Washington with one of his lowest approval scores, even though polls improved soon after his withdrawal.

According to RealClearPolitics, a CNN poll this week revealed that his approval was 37% and his disapproval was 63%, with an average net negative rating of 18 percentage points.
