President Donald Trump Jr., Ivanka Trump, and Jared Kushner will be the first people to appear at a White House briefing on Monday as part of a broader effort to assess Russia’s meddling in the 2016 presidential election.

The meeting, which is scheduled to begin at 1 p.m.

ET, will be a key opportunity for Trump and senior White House officials to address allegations of Russian interference in the election.

It is also a rare opportunity for senior administration officials to publicly address the investigation, which has been ongoing for more than two years.

It comes as the president faces growing questions about the extent of his knowledge of the matter and how he handled it during the campaign and transition.

Trump Jr.’s decision to attend the briefing has been a major blow to the administration.

It also raises the possibility that the president may not be fully in charge of the investigation and may not have fully disclosed it.

The president, who is under investigation by Special Counsel Robert Mueller, said earlier this month that he would be meeting with congressional committees to “gather information.”

He has not revealed his meetings with the congressional investigators.

The administration has said that Trump was briefed on a series of intelligence reports in early July, including on the hacking of the Democratic National Committee, a decision that was made after he learned that the intelligence was not conclusive.

Trump, who has denied any collusion with Russia, has also repeatedly questioned the credibility of the intelligence.

“We had the intel that the Democrats were hacking and stealing the information, but nobody gave a damn about it, including me,” he said at the time.

Kushner, who will serve as Trump’s personal attorney, has been in regular contact with congressional investigators and was reportedly briefed by the FBI last week.

He has said he was “very confident” that Russia did not interfere in the elections.

He and Trump Jr..

have both denied any wrongdoing and have said they have not been approached by special counsel Robert Mueller.

The White House has said there is no evidence to support the president’s claims.

But there is mounting evidence that Russia’s efforts were far-reaching.

According to a document published on Thursday by the Center for Strategic and International Studies, Russia attempted to influence the U.S. presidential election by hacking Democratic Party emails and disseminating damaging information to help Trump’s campaign.

The Center for the National Interest has compiled a dossier on Russian involvement in the U,S.

political process and alleged ties between Trump and Russia.

The report, which was compiled by the Atlantic Council’s Brent Scowcroft and Christopher Steele, was commissioned by the Senate Intelligence Committee, which released its own investigation in October into Russia’s alleged interference in last year’s election.

“Russia and the Russian government continue to be a principal actor in cyberspace, with a substantial amount of Russian military, economic, and political resources, including cyber capability, in cyberespionage,” the report said.

“The Russian Government has developed an advanced, covert, and sophisticated cyberwarfare capability.”

The document, titled “Cyber Operations: A Brief Analysis of Russian-U.S./Cyber-Assault Hybrid and Multi-National Cyber Operations, 2015-2021,” said that during the U-S.-Russian Cold War, Moscow used a range of techniques to disrupt U. S. computer networks.

It included hacking into U.N. computer systems, stealing sensitive U.K. and French government documents, interfering in U.G. elections, and interfering with U.A.E. and EU computer networks, among other things.

“Russian efforts in cyberespondence have become increasingly sophisticated, including via spear phishing, phishing campaigns targeting key organizations and individuals in the Western world, and cyber operations targeting critical infrastructure,” the document said.

It added that Russia has developed a wide range of cyberweapons and tools to conduct operations in cyberwarfare.

“In 2016, Russia also began covertly acquiring large amounts of U.F.O. information on key political figures in the United States,” the study said.

The authors also said that Russian operatives “targeted U.P.s, U.C.I.S., and U.H.I.”

The report said that Russia used cyberattacks against the U
