Senate Minority Leader Charles Schumer (D-N.Y.) on Tuesday said that he supports a decision to invite Rudy Giuliani, President Trump‘s personal lawyer, to testify before a key Senate panel, but said he must do so under oath.

„We welcome Mr. Giuliani testifying. Given the apparent depth of his involvement in the president’s effort to convince foreign governments to investigate a political rival, he must testify under oath,“ Schumer tweeted.
