House investigators want Vice President Mike Pence to give them documents that could shed light on whether he helped President Donald Trump pressure Ukraine to investigate Joe Biden.

In a letter to Pence on Friday, Oct. 4, the Democratic chairmen of three House committees cited reports that a Pence aide may have listened to the July phone call in which Trump pushed Ukraine’s president to investigate unfounded charges that Biden was involved in corrupt activities there.

They say they also want to learn more about Pence’s Sept. 1 meeting with President Volodymyr Zelenskiy.

The letter says there are “questions about any role you may have played in conveying or reinforcing the President’s stark message to the Ukrainian President.”

Vice President Mike Pence asserted to reporters on Thursday, Oct. 3, in Arizona that he did not discuss the Biden case with Zelenskiy in their Sept. 1 meeting and stressed that their talk centered around corruption and Russia ‘s invasion in Ukraine.

He, however, expressed full agreement with President Trump’s call on the Ukrainian president to investigate the Bidens’ involvement in the case of Burisma Holdings.

He said that, given the declassified transcript of the phone call between the two presidents, the impeachment inquiry pushed forward by the House Speaker Nancy Pelosi (D-Calif.), is groundless, and publicly urged Ukraine to look into the case.

President Donald Trump said on Friday, Oct. 4,  that he plans to address a letter to Pelosi that they will not comply further with the ongoing impeachment inquiry until the matter has been voted on by the full House, officials said.

On Thursday, House Minority Leader Kevin McCarthy (R-Calif.) addressed a letter to Pelosi for the suspension of the impeachment inquiry into Trump until “equitable rules and procedures” are set up, and criticized her for the “swiftness and recklessness” of the inquiry, Fox News reported.
