Lindsey Graham invites Giuliani to testify before Senate Judiciary Committee

Senate Judiciary Chairman Lindsey Graham (R-S.C.) tweeted Tuesday that he would offer Rudy Giuliani a chance to testify before the committee about his "concerns" — which have not been substantiated — that Joe Biden pressured Ukraine to fire a prosecutor investigating his son.

"Have heard on numerous occasions disturbing allegations by @RudyGiuliani about corruption in Ukraine and the many improprieties surrounding the firing of former Prosecutor General Viktor Shokin. Given the House of Representatives’ behavior, it is time for the Senate to inquire about corruption and other improprieties involving Ukraine. Therefore I will offer to Mr. Giuliani the opportunity to come before the Senate Judiciary Committee to inform the committee of his concerns."

Why it matters: Giuliani is at the center of an alleged pressure campaign by President Trump and his allies to push the Ukrainian government to investigate Biden, which has resulted in a formal impeachment inquiry being opened in the House.

• House Democrats have subpoenaed Giuliani for documents related to his interactions with Ukrainian officials, but have not yet asked him to testify — citing his combative, falsehood-laden appearances on cable news.
• Giuliani has not yet indicated whether he will comply with the subpoena, but has accused House Intelligence Chairman Adam Schiff (D-Calif.) of being "illegitimate."
• "I haven't made up my mind," Giuliani told The Daily Beast on Monday. "But one of the issues is, do you acknowledge an illicit committee?"

Worth noting: In 2016, three Republican senators signed a bipartisan letter to the government of Ukraine urging it to "press ahead with urgent reforms to the Prosecutor General’s office and judiciary" — echoing the policy pushed by Biden, the European Union and the International Monetary Fund to oust Shokin for not doing enough to battle corruption.

• Sen. Rob Portman (R-Ohio), one of the GOP senators who signed the letter, reiterated on Monday that Shokin was widely known as an ineffective prosecutor, and that Hunter and Joe Biden's involvement in Ukraine had nothing to do with the message.
