The national debt went up $8+ Trillion in Trump’s 4 years, when the border was supposedly secure. Yet, it’s only gone up $4 Trillion under Biden, when the border has been completely open. So you trying to directly correlate the two is an obvious fail. The debt goes up when spending is out of control, period.
“I want people to come into our country in the largest numbers ever, but they have to come in legally.”
Trump State of the Union 2019. Wow, the largest numbers ever. And they are coming in legally, now. How is he planning to pay for all the increases in national debt, local school budgets, housing, and even free food you said, etc?

This chart shows that the 4 trillion you state is wrong, and that the number you are stating, is for Biden's first two years, and those must fiscal years, not calendar year.
