Schumer demands GOP investigate, issue subpoena over whistleblower complaint

Schumer, in a letter to Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellBiden says he's open to altering, eliminating filibuster to advance voting rights Pelosi says GOP senators 'voted to aid and abet' voter suppression for blocking revised elections bill Manchin insists he hasn't threatened to leave Democrats MORE (R-Ky.), said Republicans should "fulfill your constitutional duty" in the wake of the whistleblower complaint, which has not been divulged to Congress. 
"In the face of this dire warning and the Trump Administration’s effort to cover it up, the Republican-led Senate has remained silent and submissive, shying away from this institution’s constitutional obligation to conduct oversight," Schumer wrote. 
"The Republican Senate’s 'see no evil, hear no evil' attitude toward such a serious national security concern is unacceptable and must change," he added.
Schumer's letter comes amid reports that both Trump and his attorney Rudy GiulianiRudy GiulianiLev Parnas found guilty of breaking campaign finance laws Giuliani associate Lev Parnas won't testify at trial Four Seasons Total Landscaping comes full circle with MSNBC special MORE have attempted to persuade Ukrainian President Volodymyr Zelensky to investigate former Vice President Joe Biden or his son.
Schumer, in his letter to McConnell, wants Senate Republicans to hold a hearing about the whistleblower complaint, including having acting Director of National Intelligence Joseph Maguire, acting Office of Management and Budget Director Russell Vought and Secretary of State Mike PompeoMike PompeoObama looks to give new momentum to McAuliffe The CIA's next mission: Strategic competition with China and Russia Biden, Trump tied in potential 2024 match-up: poll MORE testify before a Senate committee. 
Schumer also wants Republicans to issue a subpoena to force the administration to hand over the whistleblower complaint, and for the Justice Department to provide copies of any legal guidance it's given the administration on providing Congress with the whistleblower complaint. 
"This is a whistleblower complaint that has been labeled 'urgent' and 'credible' not by Democrats, but by a senior-level Trump appointee. It is the Senate’s duty to take this national security matter seriously and to take action now," Schumer added in his letter. 
Members of the House Intelligence Committee received a briefing last week from the intelligence community's inspector general but did not receive information about the complaint's contents. Maguire has refused to provide the information to the committee or comply with House Intelligence Committee Chairman Adam SchiffAdam Bennett SchiffAll eyes on Garland after Bannon contempt vote House votes to hold Bannon in contempt of Congress The Hill's 12:30 Report - Presented by Altria - Manchin heatedly dismisses rumors of leaving Democratic Party MORE's (D-Calif.) request that he hand over the complaint. 
Schumer also wants the White House to identify which official sought to delay $250 million in aid to Ukraine and for Trump to release the transcript of his call with Zelensky. 
The White House has, so far, not released a transcript of the call. Trump suggested on Sunday that the topic of discussion during his call with Zelensky “was largely the fact that we don't want our people like Vice President BidenJoe BidenOvernight Energy & Environment — Presented by American Clean Power — Methane fee faces negotiations White House rejects latest Trump claim of executive privilege The No Surprises Act:  a bill long overdue MORE and his son [contributing] to the corruption already in the Ukraine.”
Senate Republicans have for the most part remained silent about the whistleblower complaint and the ongoing battle between House Democrats and the White House for it to be shared with Congress. 

“I would urge him to continue to be as transparent as possible and tell us as much as he can without compromising executive privilege so that we can understand what happened,” he said during a radio interview with Hugh Hewitt on Monday.
