New: A key witness in the NY D.A's Trump Org probe says she's now facing threats for describing alleged crimes in an interview on The Beat. "Monday night I appeared with Michael Cohen [on The Beat]," says Jennifer Weisselberg, "I spoke about how I know [Allen Weisselberg is] hiding money in escrow... There's definitely tax fraud. There's definitely tax evasion. For the first time, they seem really nervous."

A Black woman who was removed from her car at gunpoint with four underage family members by Aurora, Colorado, police officers last year has filed a civil rights lawsuit against the city and police officials. Police incorrectly believed Brittney Gilliam had stolen the vehicle... Her attorney David Lane joined @AriMelber to discuss her case, asserting: "She was trying to show the police her registration and her license plate number matched the registration. The police wouldn't look at a piece of paper to determine that this was not a stolen car."

Did you know that most of the people in our jails are innocent? Under America's cash bail system, if you are rich, you’re innocent until proven guilty and you prepare for trial at home.

America's racial challenge is a huge issue in the Trump-era. That may sound obvious, but it is actually a long way from the misplaced talk around 2008 that "Obama's election alone somehow cured America" of all the work left to do.

When Obama won the 2008 Election, a landmark bribery case grew out of his Senate vacancy. The decision on who would be appointed to the seat fell into the hands of to Illinois Governor Rod Blagojevich – an outlandish politician who didn't follow the norms.

How did Trump's E.U. Ambassador Gordon Sondland, a hotel magnate with no diplomatic experience, get thrust into the middle of an impeachment probe? A look into his business record before his diplomatic career, shows he was never afraid to push boundaries. "As Ambassador, Sondland would continued to push the limits, renovating his official residence in Brussels, spending tens of thousands of dollars on furniture, rugs, and custom woodwork." @AriMelber on reports of Sondland spending taxpayer's money to fulfill his lavish lifestyle

THREAD: If the House decides to impeach Trump, you will be seeing more of the man who is leading the charge - House Intelligence Committee Chair Adam Schiff, who has become one of the most famous people in Washington, and a major target of Trump defenders.

THREAD: As House Dems prepare for their first floor vote on impeachment, @AriMelber breaks down Dems’ newly-released rules which could govern the process by which they continue their impeachment inquiry into President Trump.
