Senate Republican Whip John ThuneJohn Randolph ThuneRepublicans show little enthusiasm for impeachment witness swap Overnight Defense: US military jet crashes in Afghanistan | Rocket attack hits US embassy in Baghdad | Bolton bombshell rocks impeachment trial Bolton upends Trump impeachment trial  MORE (S.D.), the No. 2 Senate GOP leader, on Wednesday said it’s ultimately up to Graham whether to request the Bidens answer questions about whether they played any role in shielding a Ukrainian gas company from a corruption investigation.

But Thune warned that Graham needs to be careful about following Giuliani’s lead on investigating Biden.

“If you’re Lindsey, I’m not sure I’d be taking recommendations from Rudy Giuliani on who I bring” in front of the committee, Thune said.

Giuliani has lost some credibility with GOP lawmakers after two associates who helped him compile information on Ukrainian corruption were arrested at Washington Dulles International Airport last week trying to leave the country.

“It wouldn’t be my highest priority. We need limited bandwidth if we need to try to focus on getting things done, not contributing to the sideshow,” Cornyn said.

Sen. Chuck GrassleyCharles (Chuck) Ernest GrassleyTax season could bring more refund confusion Graham vows Biden, Ukraine probe after impeachment trial Social security emerges as latest flash point in Biden-Sanders tussle MORE (R-Iowa), the previous chairman of the Judiciary Committee, said he would want to know exactly why Joe Biden needs to appear before the panel, seeing as how the former vice president is a leading candidate to win the Democratic nomination to face Trump next year.

“I’d want to know what he wants to accomplish by bringing him before the committee,” Grassley said of Graham.

On Wednesday, Graham said he hadn’t made a decision on whether to call Joe or Hunter Biden before his committee, something Giuliani says is essential to pushing back against the impeachment effort by House Democrats.

“I don’t know yet,” Graham said. “Right now I want to see what the Intel Committee does.”

“I’m concerned about the corruption in the Ukraine. I’d like to hear from Rudy,” Graham said, calling Giuliani the “foundational witness.”

Graham added that he might subpoena Giuliani if he declines an invitation to voluntarily appear before the Judiciary Committee.

“I’m going to ask him. If I see a need to subpoena him, I will,” Graham said, adding that Giuliani would testify in an open session of the committee.

The remarks came amid an uncharacteristic public spat between Trump and Graham over the president’s decision to withdraw U.S. troops from northern Syria.

At one point, Trump said Graham should focus on investigating the 2016 election, with a focus on Obama administration officials.

“That’s what Lindsey ought to focus on,” Trump said. “That’s what the people of South Carolina want him to focus on.”

Whether the fallout of that exchange will extend to possible Biden testimony is yet to be seen.

Giuliani says that Biden and his son, who was paid as much as $50,000 a month to serve on the board of Burisma Holdings in Ukraine, should be called before Congress as part of the GOP’s defense of Trump.

Giuliani argues that Trump was acting in the nation’s interest when he asked Ukrainian President Volodymyr Zelensky in a July 25 phone call to investigate whether Biden played any role in thwarting a corruption investigation in Ukraine, which Giuliani believes was motivated by a desire to protect his son.

“If I were in the House and I had subpoena power, my first witness would be Joe Biden for Trump because I would want to show the corruption that he unleashed in Ukraine that deprived us of the information that could have exonerated the president,” Giuliani told The Hill last week. “My second witness would be Hunter.”

Trump and Giuliani have repeated unsubstantiated allegations that Biden acted corruptly in dealing with Ukraine. Giuliani believes Biden used his power as vice president to get a Ukrainian prosecutor fired to protect his son.

Graham previously dismissed the idea of bringing Joe Biden before his panel, telling reporters that he didn’t “want to turn the Senate into a circus.”

“I have no interest in opening up that front. I don’t want to blow up the Senate,” he said last month.

But he changed his mind over the two-week October recess in reaction to what he viewed as an intensification of partisan tactics by House Democrats and their impeachment inquiry into Trump.

Graham told Fox News’s Bret Baier on Tuesday that he would “look at” calling Hunter Biden to testify if Giuliani first answered questions before the panel.

Several Republican lawmakers have highlighted Hunter Biden’s cushy post as a sign of possible corruption.

“I’ve got some real legitimate questions about what happened with Vice President Biden, Hunter Biden, what was happening over there ... I have a lot of questions that should be answered,” Sen. Ron JohnsonRonald (Ron) Harold JohnsonGraham vows Biden, Ukraine probe after impeachment trial GOP warns of 'drawn out' executive privilege battle over Bolton testimony  Senate Republicans confident they'll win fight on witnesses MORE (R-Wis.), one of Trump’s regular defenders, told reporters last month.

But now there’s also a growing sense among GOP lawmakers that hauling Giuliani and Biden to testify under oath before a Senate committee could turn out to be a bad idea.

For one thing, it could put Giuliani in the uncomfortable position of having to answer questions from Democrats about how much influence he has as Trump’s private lawyer over U.S.-Ukraine policy.

“He’s apparently, unbeknownst to all of us now, carrying out missions for the president of the United States and conducting foreign policy for the U.S. This was one of the many of the surprises of the last two weeks, to find out that Rudy Giuliani and this other guy are carrying out shadow foreign policy for the U.S.,” said Sen.

Bringing Biden before the Judiciary Committee might also play into Democratic charges that Trump and his GOP allies have tried to use the power of the federal government to hamstring a political rival.

And it could also further inflame partisan tensions and make it tougher to get regular business done, as Graham said he feared when speaking to reporters last month.

Sen. Richard Blumenthal (D-Conn.) on Wednesday warned that Graham needs to have a very strong reason to call on the Bidens to testify.

“There should be a very strong reluctance to bring a presidential candidate who has no official position right now before the committee without a really strong basis, and I see no basis right now,” he said.

Other Republican members of the Judiciary panel on Wednesday said they would leave things up to Graham.
