U.S. Attorney General Jeff Sessions is sworn in prior to testifying before the U.S. Senate Intelligence Committee hearing on Capitol Hill, in Washington D.C., the United States, June 13, 2017. U.S. Attorney General Jeff Sessions strongly denied the accusation that he colluded with Russiaduring last year's Donald Trump campaign, calling it an "appalling and detestable lie." From Las Vegas' shooting spree to Manhattan's truck attack, from Texas' Hurricane Harvey to California's wildfires, from the advancing bull stock market to once-in-a-century total solar eclipse across U.S., seventeen photos covered the impressive moments of Americans through out the year.
