WASHINGTON (AP) â??�?�? House conservatives have wasted no time since returning from their summer recess showing just how tough they can make life for Speaker Paul Ryan �¢�?�? and for Democrat Hillary Clinton if she becomes president. Conservatives look determined to force a vote in coming days to impeach the head of the IRS despite deep misgivings among other Republicans about such a pre-election move. Theyâ??re pressuring Ryan to oppose a deal taking shape in the Senate on must-pass legislation to keep the government open. And theyâ??re promising to keep investigating Clintonâ??s email issues even if she ends up in the White House. Some conservatives are even saying openly that impeachment hearings should be an option against Clinton. â??There probably ought to be,â?? said Rep. Mo Brooks, R-Ala. Together the dynamics underscore the competing pressures that could confront Clinton and Ryan in a new era of divided government if she wins the presidency in November and he is re-elected speaker in January. Their relationship faces deep constraints even before it begins, in part because of a single group of people �¢�?�? the several dozen deeply conservative lawmakers who are keeping Ryan on a short leash and who are among the Republicans pushing for ongoing investigations of Clinton.
