June 8 (Reuters) - U.S. stocks were little changed in choppy late morning trading on Thursday as former FBI Director James Comey's testimony got underway.
Comey is being grilled by Washington politicians over his claims that President Donald Trump asked him to drop an investigation of former national security adviser Michael Flynn as part of a probe into Russia's alleged meddling in the 2016 presidential election.
Comey said he had no doubt that Russia interfered with the election but was confident that no votes had been altered.
"Today is about Washington and the drama surrounding Comey's testimony. But the talk about the demise of President Trump's presidency or growth agenda seems premature, short of a smoking gun," said Terry Sandven, chief equity strategist at U.S. Bank Wealth Management in Minneapolis.
"I expect equities to generally tend sideways today, short of any new revelations coming out of the testimony."
Earlier on Thursday, the European Central Bank signaled no further interest rate cuts as euro zone prospects improved but said subdued inflation meant it would continue to pump more stimulus into the region's economy.
Investors are also keeping an eye on the outcome of the UK general election, with opinion polls showing Theresa May's Conservative Party leading between 5 and 12 percentage points over the main opposition Labour Party, suggesting she would increase her majority.
