Lindsey GrahamLindsey Olin GrahamRepublicans aim to avoid war with White House over impeachment strategy New York Times editorial board calls for Trump's impeachment Graham invites Giuliani to testify about recent Ukraine trip MORE's (R-S.C.) invitation to testify before Congress about Ukraine.

“That’s a decision I’ve got to make with my client over the course of the next week or so,” Giuliani told Hill.TV on Wednesday without elaborating further.

His comment came a day after Graham changed course, and announced plans to invite the former New York City mayor to testify before before the Senate Judiciary Committee.

The senator previously indicated that he wanted "all things Ukraine" investigated but didn't think the Senate should lead the probe.

“Given the House of Representatives’ behavior, it is time for the Senate to inquire about corruption and other improprieties involving Ukraine,” Graham said in a series of tweets.

While Graham didn’t specifically mention former Vice President Joe BidenJoe BidenNew York Times editorial board calls for Trump's impeachment Graham invites Giuliani to testify about recent Ukraine trip Booker leads other 2020 Dems in petition urging DNC to change debate qualifications MORE, he added that he made the decision after hearing “numerous occasions disturbing allegations” from Giuliani about alleged corruption in Ukraine, particularly concerning the firing of the country's then-top prosecutor general Viktor Shokin.

The announcement comes as Trump and his allies double down over claims that Biden, while serving as vice president, pushed for Shokin to be fired in order to help his son, who serves on the board of a Ukrainian energy company. 

There has been no evidence of wrongdoing by the former Vice President.

Giuliani, meanwhile, has become a key figure in the ongoing House impeachment inquiry arising from Trump’s efforts to pressure Ukraine to investigate the Bidens.

House Democrats subpoenaed Giuliani last month as part of the investigation, though Giuliani denied this in his interview with Hill.TV.

“With regard to the House…I didn’t get a subpoena — I’ve gotten a letter,” he said. “They haven’t gotten to the stage of a subpoena.”
