Firstly, there is no information available about Jack Smith spending $535 million of taxpayers' money investigating Trump. It is possible that this might be a fictional or erroneous claim. Government investigations and their costs are subject to scrutiny and transparency, and such a significant expenditure would likely be a topic of public and media interest if it were true.
Regarding investigations related to Donald Trump, it is essential to note that any statements I make are based on information available . At that time, Donald Trump had faced multiple investigations during his presidency and afterward, related to various issues such as possible collusion with Russia during the 2016 election, financial dealings, and potential obstruction of justice. These investigations were led by different individuals and agencies, including special counsel Robert Mueller.
The outcomes and conclusions of these investigations are beyond my knowledge as my data only extends . If there have been new developments or investigations beyond that point, I would not be aware of them.
As for the U.S. Supreme Court, their decisions are unpredictable and depend on the legal arguments and evidence presented during appeals. Whether they would "let him go" on appeal would depend on the specific case, its merits, and the interpretation of the law by the justices.
For up-to-date and accurate information on any ongoing investigations, legal proceedings, or political developments, I recommend consulting reliable news sources.
