House Republicans move closer to impeachment inquiry

House Republicans are moving closer to opening an impeachment inquiry after the transcribed interviews and public testimony earlier this summer by two IRS whistleblowers regarding the government's handling of its investigation into President Joe Biden's son, Hunter Biden. 

The whistleblower testimony about the probe was a "game changer" according to a senior GOP aide, who told CBS News that with what House Republicans believe is significant new evidence uncovered by GOP-led committee investigators, the "momentum is going toward opening an impeachment inquiry." 

The aide said September would be a pivotal month, with the anticipated testimony of Attorney General Merrick Garland before the House Judiciary Committee. Garland is expected to be pressed by Republicans about apparent discrepancies in statements about the authority held by then-U.S. Attorney David Weiss to bring charges in the five-year investigation of Hunter Biden.
