"This is extremely troublesome and it really does require a congressional hearing," Cardin, who is the ranking Democrat on the Senate Foreign Relations Committee, told CNN's Wolf Blitzer.
"First of all, we know that WikiLeaks has been working with Russia in regards to what happened in our election. Now we know there was communication between WikiLeaks and Donald Trump Jr. about using the information of WikiLeaks," he said.
"Shortly thereafter, candidate Donald Trump issued a tweet in regards to WikiLeaks. This is more than just having information that’s interesting," he continued.
Cardin's comments come after it was revealed that Trump Jr. communicated privately with WikiLeaks during the presidential campaign.
The WikiLeaks Twitter account had sent a direct message to the president's eldest son in September 2016 alerting him that an anti-Trump site run by a political action committee was “about to launch.” The message offered the password to the site.
Trump Jr. later confirmed the correspondence in a tweet on Monday.
