"What have the Russians done to deserve getting them back? The dacha on the Eastern Shore of Maryland is just an intelligence collection facility. That's all it is. And so I don't see any reason as a freebie to even talk about giving them back," Clapper said on Friday.
Brennan said he agreed with Clapper.
"For what purpose and why at this stage? Maybe in the future if we're able to get on a better track with Russia over time," Brennan said. "But at this time now, I don't see any earthly reason to do that."
In December 2016, the Obama administration imposed sanctions against Russia over its alleged meddling in the 2016 US presidential election, and expelled 35 Russian diplomats and closed two Russian diplomatic compounds in New York and Maryland.
Russian officials have repeatedly denied the allegations of meddling in US elections, calling them absurd and created to deflect public opinion from pressing domestic issues.
