Over his two terms, Mr. Trump has pardoned or commuted the sentences of a raft of former Republican members of the House. Among those receiving such grants were Duke Cunningham, of California, who was convicted of taking over $2 million in bribes, among other crimes; Duncan Hunter, also of California, who pocketed thousands of dollars of campaign contributions and spent it on extramarital affairs; Rick Renzi, of Arizona, who was convicted of racketeering and extortion; Robin Hayes, of North Carolina, who lied to investigators in a bribery investigation; Chris Collins, of New York, who pleaded guilty to insider trading and false statements; Michael Grimm, also of New York, who pleaded guilty to tax evasion and also admitted in court that he committed perjury and hired undocumented immigrants; John Rowland, of Connecticut, a former governor as well as congressman, who pleaded guilty to election fraud after going to prison years earlier in a separate scandal; and Steve Stockman, of Texas, who was released after serving only two years of a 10-year sentence for stealing upward of $1 million.
