The Republican-led impeachment inquiry into President Joe Biden has hit a roadblock as House Oversight Committee Chairman James Comer reportedly grows increasingly frustrated with the investigation’s lack of progress. Comer is said to be considering closing the inquiry as he eyes higher office ambitions. Despite denials from the committee, sources indicate that the investigation is winding down. Comer has also drawn criticism from fellow Republicans for his handling of the probe, with some suggesting he may have overreached in his claims against Biden.
