Young Americans believe nearly half of the news shared on Facebook is false and President Donald Trump tweets too much. They also want to help unite America but find public service unappealing. Those are among the findings from recent interviews with 2,600 young Americans -- aged 18 - 29 -- by Harvard University’s Institute of Politics. The poll, released Tuesday, found 81 percent of young people questioned by Harvard use Facebook. But most consider a lot of the news on Facebook to be untrue. Earlier this month, Facebook said it is removing accounts of people who send out fake news stories. The poll also found that 68 percent of young people believe President Trump tweets too much. Only 11 percent say his tweets are appropriate.
