Edward R. Martin Jr.’s conduct is part of a pattern in which top administration officials try to use the vast powers of the government to cast the specter of criminality on President Trump’s enemies.
Edward R. Martin Jr. has said that if he is unable to successfully obtain indictments against the targets of his inquiries, he will name and shame them.
