The dollar was flat Thursday as the market assessed the fallout from Trump’s sacking of FBI Director James Comey.
The dollar index was off 0.03% at 99.47 at 02:45 ET.

The dollar remains supported by expectations of further U.S. tightening this year.
The pound was steady at the $1.29 mark ahead of the BoE rate decision and inflation report.
