Are there any checks on Trump's financial behaviors and self-enrichment?

According to Eric Lipton of The New York Times, the infrastructure around accountability has been 'largely demolished' regarding Trump's financial behaviors. This comes after what Nicolle Wallace described as a 'remarkable line crossed' when Trump was enriching himself with US taxpayer funds during his administration. Lipton suggests that Trump appears to have developed a 'much broader money making aperture' in what Wallace calls 'Trump 2.0,' indicating an expanded approach to personal enrichment. The discussion highlights the concerning absence of functional checks and balances to prevent such behaviors in governance.
