June 8 (Reuters) - U.S. stocks were higher in early afternoon trading on Thursday after former FBI Director James Comey's testimony was seen by investors as having no smoking gun that could affect Donald Trump's presidency.
Comey, who was investigating alleged Russian meddling in the 2016 U.S. presidential election, said he had no doubt that Russia interfered with the election, but was confident that no votes had been altered.
Comey said he was disturbed by Trump's bid to get him to drop a probe into former national security adviser, Michael Flynn, but would not say whether he thought the president sought to obstruct justice.
Investors were concerned that any major revelation by Comey could dampen already flagging momentum for Trump's agenda of lower taxes and lax regulations.
Bets that Trump can implement his agenda are partly behind a rally that has taken stock indexes to record highs.
"I think the market is taking less of an alarmist review of this situation because there is no smoking gun here. So it's not particularly impactful for thinking about ... Trump's economic agenda to go through," said Thomas Simons, money market economist at Jefferies & Co in New York.
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 awaiting the results of the UK general election. Opinion polls show Theresa May's Conservative Party leading between 5 and 12 percentage points over the main opposition Labour Party, suggesting she would increase her majority.
"The market cares because if Theresa May loses the majority that would be disruptive of the Brexit process," said Art Hogan, chief market strategist at Wunderlich Securities in New York.
"Getting back into something that seemed to be a fair and orderly process into something that's going to be more disruptive would not be a market positive."
At 12:36 p.m. ET (1636 GMT), the Dow Jones Industrial Average was up 68.55 points, or 0.32 percent, at 21,242.24 and the S&P 500 was up 4.06 points, or 0.16 percent, at 2,437.2.
