The strongest and weakest currencies as NA traders enter for the day

The JPY is the strongest. The AUD is the weakest.  
As North American traders enter for the day, the JPY is the strongest while the AUD is the weakest. US yields are lower. The stock markets are lower in Europe. The US pre-market indices are also lower with the S&P down -10.25 points, the Nasdaq down -21 points and the Dow futures down -85 points. There are concerns out of Washington with the newest Comey email the latest fire to put out.  Less unity, makes the Trump agenda more difficult to enact.    The fallout is impacting the JPY pairs on a flow into the "safe haven" (and less growth).   The USD is lower on the concerns although it is marginally higher vs. the "riskier" AUD and CAD.
