Federal Reserve Chairman Jerome Powell testifies Tuesday and Wednesday in the first of his twice-a-year economic updates to Congress.

3. New Hampshire primary pits Sanders against Buttigieg
New Hampshire residents vote Tuesday in the first-in-the-nation primary, eight days after the botched Iowa caucuses which saw former Mayor Pete Buttigieg edging Sen. Bernie Sanders for the most delegates. Sanders was polling first in New Hampshire with Buttigieg in second. Just after midnight, in an annual tradition in the tiny community of Dixville Notch, five residents cast their ballots. Three write-in votes went to billionaire ex-New York City Mayor Mike Bloomberg. One of those write-ins was in the Republican primary. Sanders and Buttigieg split the other two votes. Voters registered as "undeclared" in New Hampshire can vote in either party primary.
