This is not just an impression, it is macroeconomics 101. If government goes into (more) debt and spends that money it increases inflation. Of course, all of this is not very easy. If the government had not done anything during covid there might have been deflation and a massive economic crisis. Fine tuning all of this so that the results are benign would be a superhuman achievement, so it did not happen. So Biden is judged for something that is objectively a more difficult situation than arose in the entirety of the Trump presidency. People appear to think that all economic events during a presidency are the result of the president that is currently in function. That is of course ludicrous. Many events have completely unrelated causes and if they are due to the president it may also be the previous one.

If that spending creates an imbalance of money vs goods.
The problem with the COVID recovery is that goods availability declined, and as a consequence the economy would have taken a nosedive via compounding effects.
Unfortunately, flooding the market with money (which all countries, not just the US did) masked the problem long enough for supply to renormalize... but in the process ballooned the numerator while the denominator was still temporarily low.
Of course that's going to cause price inflation.
And then when supply returns to normal, of course companies are going to try to retain that new margin as profit, instead of decreasing prices.
