NBC Washington Correspondent Yamiche Alcindor and former U.S. Attorney Barbara McQuade join Andrea Mitchell to discuss key challenges facing the January 6 Committee ahead of their primetime hearings this week: getting a "distracted nation" to pay attention and understand what's at stake. “I think the biggest challenge for lawmakers here, as they talk about these sort of huge ideas of American democracy and sort of the experiment that we're all living in, benefiting from, possibly being brought to his knees, is whether or not they can make people care,” says Alcindor. “The American public has been groomed to expect high value quick entertainment,” says McQuade.

Trump (@realDonaldTrump) February 25, 2019 The left loves to hate on Trump, calling him a racist and what not. I know Trump can be juvenile sometimes – certainly – but the racist and hateful name-calling is just what it is, garbage.

Alexandria Ocasio-Cortez scrambled Sunday to explain why neighbors at her listed Bronx address never saw her there — and ended up claiming she recently relocatedto a larger place nearby. The day after The Post reported that residents said they had never seen her around — and she ducked questions about it after an appearance — her spokesman said the Democratic freshman congresswoman now lives with her boyfriend in a two-bedroom apartment “a block and a half away.’’ The pair relocated there earlier this month, he said. “She lives in the same neighborhood she’s lived in for years,” said the spokesman, Corbin Trent. “She is not living in the exact same condo.’’ The recent move still didn’t explain why residents at her previous digs — a one-bedroom Bronx condo owned by her mom — insisted they had never seen her there. U.S. reps and senators are required to have a residence in their home districts. Trent claimed that Ocasio-Cortez, 29, was at her new home Sunday afternoon, al
