Cornyn, speaking to reporters outside of the Judiciary Committee, said that he could "understand [Trump Jr.'s] frustration" and warned that 'at some point … this smacks of politics."

"At some point this is not about finding facts, this smacks of politics and I think we have an important job to do to try to keep the Intelligence Committee out of politics and just keep ourselves focused on our mission, which is oversight of the Intelligence Community," said Cornyn, who is an advisor to Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellTurkey sanctions face possible wall in GOP Senate Fox's Wallace says 'well-connected' Republican told him there's a 20 percent chance GOP will vote for impeachment White House staggers after tumultuous 48 hours MORE (R-Ky.).

Pressed if he was saying he thought Burr's actions were "more about politics and not about following up on leads," Cornyn added that he "didn't say that." 

"I think the committee’s been doing important work that’s been done on a bipartisan basis, and it really is about finding out what the facts are and what we need to do to prevent foreign interference in the future. I can understand Mr. Trump’s frustration now that the Mueller report has gone public and finding no evidence of collusion. I can understand his frustration at being requested to come back," Cornyn continued.

The decision to subpoena Trump Jr. has sparked GOP criticism of Burr, who as chairman has been leading the committee's investigation. The panel has been running a years-long investigation into the 2016 election and Russian meddling.

Cornyn said on Thursday that he would talk with Burr about "what we need to do to wrap up our investigation." 

"I wasn’t aware the subpoena was issued, it was really something done by committee staff, so I’m going to talk to the chairman and the other committee members and find out exactly where we are and what else we need to do to wrap up this investigation and report our findings to the public," he said. 

Republicans argue the move is out of line with McConnell's proclamation earlier this week from the Senate floor that the Mueller investigation is "case closed," though the subpoena was issued at least a week before McConnell's speech.
