President Barack Obama is ordering an investigation into possible Russia-led hacking attempts intended to influence the 2016 election, White House counterterrorism adviser Lisa Monaco said Friday, according to Bloomberg News.

Monaco made the announcement at a breakfast hosted by the Christian Science Monitor in the nation’s capital, Bloomberg reported. Monaco said that the report from the investigation will be released to Congress before Obama leaves office but not necessarily be made public.

“We may be crossing into a new threshold and it’s incumbent upon us to take stock of that,” Monaco said, according to the site.

This comes as several lawmakers from both sides of the aisle have called for an investigation into possible Russian interference into the U.S. election. Most notably, Sen. Lindsey Graham (R-SC) has called for a probe.

Trump, for his part, has disputed claims that Russia would interfere with the election in his favor.
