The NY State criminal trial that is about to begin on April 15th is all about whether former President Donald Trump lied in his expense reports to cover up his payment of hush money to pornographic film star Stormy Daniels prior to the 2016 presidential election. NY argues that in doing this Trump violated NY State laws, almost all of which involve misdemeanor offenses. The prosecution implies that Trump's alleged lies and coverup are a violation of federal campaign finance laws, which makes the misdemeanors more serious and justifies the prosecution.
First, it is settled U.S. Department of Justice (DOJ) policy not to prosecute such cases, which is one of many possible reasons why the federal government has not brought any charges against Trump about the Stormy Daniels hush money matter. Another reason is that the DOJ may think Donald Trump's expense reports were truthful as Trump claims them to be. Second, when former President Bill Clinton perjured himself and engaged in obstruction of justice by denying under oath that he had had sexual relations with then-White House intern Monica Lewinsky, both in a deposition and before a federal grand jury, the judgment of the U.S. Senate was that Bill Clinton's "lies about sex under oath" did not disqualify him from holding the presidency.
430 law professors signed a letter to the Senate on November 6, 1998 writing that "making false statements about sexual improprieties" under oath before a federal grand jury "is not a sufficient constitutional basis to justify the trial and removal of the President of the United States." Harvard Law Professor Cass Sunstein wrote on October 4, 1998 in The Washington Post that mere lies about sex under oath were not in his view disqualifying behavior in a president of the United States.
