​President Trump​ ​in a tweet Thursday singled out former Homeland Security ​Secretary​ Jeh Johnson’s testimony before a House panel investigating Russia as ​proof​ “no grand scheme” existed between ​him and Moscow.

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

Johnson, who served under President Obama, told the House Intelligence Committee on Wednesday that Russian President Vladimir Putin “plain and simple” directed cyberattacks on the 2016 presidential election, but the interference didn’t “alter ballots, ballot counts or reporting of election results.”

Trump also questioned why the Obama administration didn’t do more to stop the hacking by Russian operatives that occurred last summer and fall.

​”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 asked.​

​Johnson told the panel that ​the Obama administration was cautious about going public on Russia’s involvement, fearing they would appear to be meddling, especially after Trump warned on the campaign trail that the election would be “rigged” for Hillary Clinton.

“We were very concerned that we would not be perceived as taking sides in the election, injecting ourselves into a very heated campaign​,” he told the panel.

Trump also blasted the Democratic National Committee, which was hacked and had its emails posted on WikiLeaks, turned down offers from DHS to help shore up its systems.

“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!​,” Trump said.​

In his testimony, Johnson said the DNC shrugged off the help.

“The FBI and the DNC had been in contact with each other months before about the intrusion,” Johnson said, “and the DNC did not feel it needed DHS’ assistance at the time.”

He also used Johnson’s testimony to support his argument that the probes into Russian involvement in the election are just a way for Democrats to get back at him for beating Clinton.

“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!” he said.
