President Donald Trump has already made history as both the first convicted felon president, as well as the second American president to be elected to two non-consecutive terms in office. Now, a Republican congressman is looking to extend Trump’s unusual presidency by proposing a constitutional amendment to allow Trump to run yet again.

Donald Trump’s second inauguration as the 47th President of the United States took place on Monday in Washington, D.C. Following tradition, the day began with a worship service at St. John’s Episcopal Church and a White House meeting between incoming and outgoing presidents.

Donald Trump will make history when he is sworn into office today as the oldest President to take the oath of office.

As Barack, 63, Bill, 78, and Hillary, 77, entered the U.S. Capitol rotunda in Washington, D.C., on Monday for the 78-year-old’s historic swearing-in ceremony, people at the Capitol One Arena could be heard loudly booing.

Just ten days ago, at Jimmy Carter's state funeral at Washington National Cathedral today, all five living U.S. presidents attended: Bill Clinton, George W. Bush, Barack Obama, Donald Trump, and Joe Biden. Today, all five men were once again in the same place, as Clinton, Bush, Obama, and Biden attended Trump's inauguration.

Former Presidents Bill Clinton, George W. Bush and Barack Obama would not be able to serve a third term because they served two consecutive terms.

Bill and Hillary Clinton have arrived at Donald Trump’s inauguration. The prominent Democratic couple showed a united front as they walked into the U.S. Capitol in Washington, D.C., for the ceremony.

Trump become only the second President in US history, after Grover Cleavland in 1893, to return to power after being voted out of the White House.

The men who held the nation’s highest office before President Trump have all remained mum on his taking the presidency on Monday.

Former Presidents Barack Obama, Bill Clinton, and George W. Bush were not in attendance at President Donald Trump’s inaugural luncheon. Despite missing the luncheon, however, all three former presidents attended Trump’s swearing-in ceremony.

“CBS Mornings” co-host Gayle King, in her live coverage of the inauguration of President Donald Trump, said: “I have to say, I’m looking at this crowd, I do not see many people of color. Does any — does anybody else besides me observe that? I’m fascinated by why that is.”
