Harvard Law professor emeritus Alan Dershowitz says impeachment "isn't constitutionally permissible," and members of the liberal media should stop calling for Democrats to impeach President Trump."I stand up for civil\u00a0liberties no matter who the\u00a0president is," Dershowitz, a Democrat who endorsed former Secretary of State Hillary Clinton's candidacy for president in 2008, said Wednesday night\u00a0on "Hannity.""If Hillary Clinton had been\u00a0elected president and they were\u00a0trying to impeach her, I would've\u00a0written a book called 'The Case\u00a0Against Impeaching Hillary Clinton.' Congress can't impeach\u00a0President Trump.\u00a0The\u00a0Constitution provides criteria\u00a0for impeachment;\u00a0treason, bribery, high crimes\u00a0and misdemeanors."DERSHOWITZ, TRIBE SPAR OVER IMPEACHMENT: YOU'D HAVE 'GONE APOPLECTIC' IF CLINTONS RECEIVED SAME TREATMENTHouse Speaker\u00a0Nancy Pelosi, D-Calif.,\u00a0in recent weeks has tried to tamp down members of her party clamoring to impeach the president over the Russia investigation, to little avail.The Hill\u00a0media reporter\u00a0Joe Concha\u00a0said Democrats calling for impeachment, such as\u00a0South Carolina Rep. Jim Clyburn, the third-highest-ranking Democrat in the House, have not been "aligned with the American people."Concha cited a Quinnipiac poll Wednesday that stated only one-third of Americans thought\u00a0Congress should launch\u00a0impeachment proceedings against\u00a0President Trump. He cited the tense confirmation hearings for Justice Brett Kavanaugh ahead of his appointment to the Supreme Court."Remember the Kavanaugh\u00a0hearings and what that did from a\u00a0ratings perspective across the\u00a0board. It would be like a\u00a0steroid shot for these networks\u00a0that are struggling right now\u00a0post Mueller report because they're not trusted and\u00a0there's fatigue around these\u00a0sorts of things," Concha said on "Hannity."The same Quinnipiac poll also showed that 69 percent of American voters believed any sitting president should be subject to criminal charges, while 24 percent said\u00a0a president should be charged with crimes after he or she leaves office."I want to make sure\u00a0every American, conservative,\u00a0liberal, centrist, right, or\u00a0left supports the Constitution\u00a0and supports civil liberties no\u00a0matter who the target is because today it's a Republican,\u00a0tomorrow it can be a Democrat, the day after tomorrow it can be you," Dershowitz cautioned. "Preserve your constitutional\u00a0rights and\u00a0civil liberties and don't let politics interfere with civil liberties and constitutional law."Concha also pointed to what he called a double standard in media coverage of the 2020 elections, calling out NBC's host Rachel Maddow, one of five moderators picked by the network for an\u00a0upcoming presidential primary debate."Objective people\u00a0look at her moderating a debate\u00a0and saying, wait a minute,\u00a0that can't happen, because in 2016 she moderated a\u00a0debate and went up on stage on national television and hugged Bernie Sanders and\u00a0Hillary Clinton on stage," Concha said.CLICK HERE FOR THE FOX NEWS APPHe compared it to the perception of certain Fox News journalists. "Picture Shannon Bream or\u00a0Martha MacCallum doing that to\u00a0a Republican candidate.\u00a0The apocalypse would look like\u00a0nothing compared to what the reaction would be."Dershowitz urged the media to put party politics aside and "get back to Walter\u00a0Cronkite-type journalism where\u00a0people can trust what they hear\u00a0in the media. Today that's just not the case," he said.
