President Trump questioned whether Russians really did interfere in the 2016 election in a series of tweets Thursday, and said those claims are being used by Democrats as an "excuse for losing the election."

"By the way, if Russia was working so hard on the 2016 Election, it all took place during the Obama Admin. Why didn't they stop them?" Trump said on Twitter.

"...Why did Democratic National Committee turn down the DHS offer to protect against hacks (long prior to election). It's all a big Dem HOAX!" he said in a second tweet.

"...Why did the DNC REFUSE to turn over its Server to the FBI, and still hasn't? It's all a big Dem scam and excuse for losing the election!" the president continued.

The Democratic National Committee pushed back against Trump and said his comments were an attempt to distract from his legislative agenda.

"The intelligence community has no doubt that the Russians attacked the DNC in an effort to disrupt our election," DNC spokeswoman Adrienne Watson said in a statement. "The only person who disputes this is Donald Trump, who has shown zero interest in protecting our country from future attacks and is now trying to distract Americans from his devastating healthcare repeal."

Members of the intelligence community generally agree Russian hackers infiltrated the DNC's computer network, as well as other entities, and attempted to meddle in the election by releasing those emails.

Officials with the FBI and Department of Homeland Security also said yesterday that Russia tried to hack into the election systems of 21 states.

But former Homeland Security Secretary Jeh Johnson told the House Intelligence Committee on Wednesday that the DNC said it didn't want help from the department's cybersecurity analysts in pathing its vulnerabilities.

Former DNC Chairwoman Debbie Wasserman Schultz, D-Fla., disagreed with Johnson's testimony and said no one from the FBI or Department of Homeland Security contacted her.

Trump has maintained the FBI's investigation into Russian interference in the 2016 election is a "witch hunt" and "fake news." This week, White House press secretary Sean Spicer declined to definitively say whether the president actually believes Russia meddled in the election.

"I have not sat down and talked to him about that specific thing," Spicer told reporters Tuesday. "Obviously we've been dealing with a lot of other issues today. I'd be glad to touch base."
