"Is there any reason for it"

The $1.9 Trillion American Rescue Plan:

"It all began with the passage of the $8.3 billion Coronavirus Preparedness and Response Supplemental Appropriations Act, 2020, enacted into law on March 6, 2020. The $192 billion Families First Coronavirus Response Act came next on March 18.

With the passage and signing of the CARES Act into law, March 27, 2020, Congress and President Trump set into motion a massive $2.2 trillion COVID-19 relief bill and the largest single economic rescue plan in the history of the U.S.

An interim funding bill—known as the Paycheck Protection Program and Health Care Enhancement Act—added $484 billion to that total. And in December 2020, the Consolidated Appropriations Act, 2021, was passed, adding another $900 billion in economic relief amid the ongoing fallout from the COVID-19 pandemic.1
