President Trump said Thursday morning the Obama administration should've done more to stop Russian interference in the 2016 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 his Twitter account.

Officials with the Department of Homeland Security and FBI told the Senate Intelligence Committee on Wednesday that Russia targeted the election systems of 21 states last year.

Though the federal government had that information as early as August, it wasn't publicly disclosed until October.

Members of the intelligence community have said before they believe Russia hacked the Democratic National Committee and other entities in an attempt to influence the election.

Despite Russia's hacking of the election systems, former Homeland Security Secretary Jeh Johnson said during testimony before the House Intelligence Committee Wednesday that no votes were actually changed.

During his testimony, Johnson said one of the reasons the Obama administration was cautious about revealing more about Russia's meddling was Trump's frequent claims that the election would be rigged against him.

In a separate tweet, Trump referenced Johnson's testimony, and specifically when he told lawmakers he didn't see evidence of collusion between the Trump campaign and Russian officials.

"Former Homeland Security Advisor Jeh Johnson is latest top intelligence official to state there was no grand scheme between Trump & Russia," the president said on his Twitter account.

Democrats also agree that despite the multiple investigations into ties between Trump campaign associates and Russia, there has yet to be any evidence showing the campaign colluded with the Kremlin.
