Re “Can a Sitting President Be Indicted?,” by Adam Liptak (Sidebar, May 30):

President Trump may be immune to criminal prosecution for acts committed after Jan. 20, but can a sitting president be charged for alleged crimes committed before becoming president?

The Paula Jones action against President Clinton seems to leave open Mr. Trump’s vulnerability to some 75 claims now working their way through the courts, to say nothing of whether the F.B.I. uncovers improper dealings with Russians before the inauguration.

Would a criminal finding against the president in any of those cases affect his stay in office, separate from an impeachment proceeding?
