You said previously that from 2021-2024 the debt levelled off. That is incorrect as shown by the link below:
https://fred.stlouisfed.org/graph/?id=GFDEBTN,
Now, from Q1 '21 TO Q1 '24 the debt has risen by a further 6.4T, with only H2 '21 significantly affected by Covid,
Most of Trump's extraordinary extra debt total (4T) was accrued in 2020 due to the Covid outbreak.
The debt certainly has not "levelled off" under Biden - it has taken off again and is now up by 1T per quarter. Insane.
