Trump vows comeback as parties clash over Democrat prosecution threats

• Donald Trump vowed a political comeback Sunday as the major parties clashed over Democrat threats to prosecute top administration officials after the president's Republicans lost control of Congress in midterm elections.
• The devastating results in last Tuesday's vote leave Trump politically hamstrung as he enters the remaining two-year 'lame duck' period of his White House tenure.
• It also opens the door to multiple investigations by the Democrat-controlled Congress of the president, his family and senior members of his administration.
