Trump's legal and political calendars collide less than a week before Iowa caucuses

With political rivals trying to make inroads into Donald Trump's formidable polling lead in Iowa days before the caucuses, the former president walked into a court hearing in Washington, D.C., that he didn't need to attend, using the legal proceeding to try to show primary voters he's being unjustly victimized by the government.

The legal turmoil surrounding Trump, who faces 91 counts in four different cases, would be expected to sink any other presidential contender's White House ambitions. 

But this week was the latest sign that the former president and his allies are keen on playing up the charges, not hiding them.
