The dollar rose to a 10-day high against a basket of currencies on Friday, boosted by a weaker British pound after Prime Minister Theresa May's Conservative Party lost its parliamentary
majority in national elections.
The dollar index, which tracks the greenback against six major rivals, was up 0.46 percent at 97.364.
The index had fallen to a seven-month low midweek on caution ahead of U.S. Senate testimony by former FBI Director James Comey and the British election. But on Friday, it added to gains from the previous session.
Comey on Thursday accused President Donald Trump of firing him to try to undermine the bureau's investigation of possible collusion between his 2016 presidential campaign team and Russia, but did not say whether he thought the president sought to obstruct justice.
