The CIA concluded on Friday that Russia's motive was to help Mr Trump.
Mr McConnell and Mr Ryan said their respective intelligence committees would investigate the allegations.
"Any foreign breach of our cyber-security measures is disturbing and I strongly condemn any such efforts," Senator McConnell told reporters, adding that "the Russians are not our friends".
Mr Ryan echoed these remarks, but warned against exploiting the work of the intelligence community for "partisan purposes".
"As we work to protect our democracy from foreign influence, we should not cast doubt on the clear and decisive outcome of this election," he said in a statement posted on Twitter.
The remarks came amid suggestions by Mr Trump that the claims were politically motivated.

Then on Monday he tweeted: "Can you imagine if the election results were the opposite and WE tried to play the Russia/CIA card. It would be called conspiracy theory!
"Unless you catch 'hackers' in the act, it is very hard to determine who was doing the hacking. Why wasn't this brought up before election?"
