GOP doubts Yellen's debt ceiling deadline as default looms.

Republicans in the House are expressing doubt about the June 1 deadline set by Treasury Secretary Janet Yellen for lawmakers to raise the debt ceiling, with some calling for Yellen to "show her work" and reasoning behind the date. While Republican leadership is not yet entertaining blowing past the deadline without acting to raise the debt limit, skepticism about the deadline's legitimacy could make reaching a deal by June 1 even less likely. The skepticism is fueling the right flank's argument that Republicans should not give in on their debt limit increase demands, viewing Yellen's threats as creating manufactured deadline pressure.
