evidence: House Speaker Kevin McCarthy announced Tuesday he is calling on his committees to open a formal impeachment inquiry into President Joe Biden, even as they have yet to prove allegations he directly profited off his son’s foreign business deals. [...] But McCarthy is facing an increasingly impatient right flank among House Republicans. His announcement came just hours before conservative Republican Rep. Matt Gaetz – who has been agitating for the effort to formally launch an impeachment inquiry – brought forward a motion to remove McCarthy as speaker if he does not comply with his list of demands. [...] According to a GOP source, McCarthy’s announcement that he’s "directing committees" to open a formal inquiry means there will be no floor vote to formally authorize the effort – marking a reversal for the House speaker from comments he previously made. McCarthy had been weighing skipping an impeachment inquiry vote – and received criticism from Democrats for being hypocritical, since he once criticized Democrats for contemplating the same – McCarthy then gave a statement to Breitbart vowing to hold a floor vote if they go that route.
