Intelligence agencies will brief President Obama Thursday on Russia's alleged role in cyberattacks in U.S. presidential elections, ABC News reports.

Obama had requested a classified report detailing any cyberattacks in presidential elections dating back to 2008.

The briefings will be conducted by the heads of the office of the director of national intelligence, the National Security Agency, the FBI and the CIA.

Officials told ABC that an unclassified version of the report will be made public Monday. Congress will also receive a classified briefing Monday.

The FBI and CIA are in agreement that Russia intervened in the election to help Trump win the White House.

But Trump has publicly cast doubt on the findings by referencing the intelligence community's false conclusions about the presence of weapons of mass destruction in Iraq.

Obama last week announced sanctions against Russia for its alleged involvement in the elections, closing two Russian compounds in the United States and ordering 35 Russian diplomats to leave the U.S.
