President Donald Trump's administration has been the focus of independent investigations by the Federal Bureau of Investigation and several congressional panels over alleged Russian meddling in the 2016 presidential election and potential collusion by the Trump campaign.
U.S. economic data on Wednesday was mixed.
Pending home sales fell for a second straight month in April, hindered by a lack of supply, while an index of U.S. Midwest manufacturing activity rose in May.
These reports have little bearing on expectations for next month's expected tightening by the Federal Reserve, although the number of hikes this year is still up for debate.
The focus will be on Friday's U.S. non-farm payrolls report, which could set the dollar's tone in the short term. A Reuters poll showed Wall Street economists forecasting 185,000 new jobs this month.
Britain's pound, meanwhile, recovered from a half a percent drop on Wednesday after a poll showed the country's ruling Conservative party still in the lead, overriding a previous projection of a hung parliament in elections next week. In afternoon trade, the dollar was down 0.23 percent at 110.54 yen after earlier falling to two-week lows.
The euro was up 0.46 percent at $1.1235, while the dollar index fell to 96.98.
Sterling, on the other hand, was up 0.25 percent at $1.2889 , recovering from a low of $1.2770 hit in London trading.
