WASHINGTON (AP) – House Republicans are pledging tough questioning of special counsel Robert Mueller when he testifies before Congress this week as Democrats plan to air evidence of wrongdoing by President Donald Trump in a potentially last-ditch bid to impeach him. Rep. Doug Collins, the top Republican on House Judiciary Committee, said the American public is growing weary of the Russia investigation three months after the release of the special counsel’s 448-page report. Both sides seemed to agree that Mueller’s testimony could be pivotal in shifting public opinion on the question of “holding the president accountable.” New York Rep. Jerrold Nadler, chairman of the Judiciary Committee said Mueller’s report lays out “very substantial evidence” that Trump is guilty of “high crimes and misdemeanors,” the constitutional standard for impeachment.
