Trump didn't place his hand on the Bible during his swearing-in, and some of his supporters are blaming John Roberts.

Donald Trump took the oath of office on Monday, promising a sweeping series of executive orders upon his return to the presidency.

Theodore Roosevelt did not use a Bible when he was sworn in following the death of President William McKinley in 1901. Lyndon Johnson had his hand on a Catholic missal, or prayer book, when he took the oath aboard Air Force One after the assassination of President John F. Kennedy in 1963.
