Trump is “at the center of [a] whistleblower complaint, lodged in August, alleging that he repeatedly solicited foreign interference in the 2020 election from Ukraine. That complaint is the catalyst for a formal House impeachment inquiry into the president”.

NPR reported Sunday that a lawyer had said a second whistleblower with direct knowledge of Ukraine call had stepped forward. Many would have thought that this second whistleblower is how far things can get complicated for Trump in the impeachment investigation.

But Independent reported four days ago that before Donald Trump’s phone call with his Ukrainian counterpart sparked the whistleblower complaint that might lead to impeachment, another whistleblower had filed a different complaint, this one related to the president’s tax returns. This has made matters worse for Trump as the Democratic party ramps up efforts towards the impeachment inquiry.

According to Business Insider, “in an August 8 letter to Treasury Secretary Steven Mnuchin, Rep. Richard Neal, the chairman of the House Ways and Means Committee, said his committee received credible allegations of “evidence of possible misconduct” from a federal employee in July.”

Business Insider also noted that “though the president is not required by law to release their tax returns, every president except Trump has voluntarily released their tax returns or a tax summary since 1974⁠.
