The headline here from earlier: Senate GOP: Said to consider 1 year corporate tax cut delay - WAPO
As you'd expect the USD has slipped on the news
Update:
'Overnight' US equity index futures are lower also.
On USD/JPY, watch 113.50/55 - there are stop loss (sell) orders building under there.
ps. the link to the Washington Post article is in that post linke above
