'Start Here': House Democrats begin to make their case against Trump

Here's what you need to know to start your day.

It's Thursday, Jan. 23, 2019. Let's start here.

1. The managers

On the first of their three days of opening arguments in the Senate trial, the House impeachment managers began making their case against President Donald Trump, accusing him of abuse of power and obstruction of Congress.

Rep. Adam Schiff, (D-Calif.) a House manager in the trial, "attempted to bring all of these threads of the Ukraine affair together for senators," especially for those who didn't follow testimony from the impeachment hearings, says ABC News' Katherine Faulders on "Start Here."

"Now it's their job as the House impeachment managers to present what they say are the facts to the senators who have not connected the dots," she tells the podcast.

Before heading back to Washington, D.C. from the World Economic Forum in Davos, Switzerland, the president blasted the Democratic House managers for bringing the case to the Senate, "They had no case. It's all a hoax."

2. Weinstein trial underway

The rape and sexual assault trial of disgraced Hollywood producer Harvey Weinstein is now underway in New York.

In opening arguments, prosecutors called Weinstein a sexual predator and a rapist, and outlined their case with six women testifying against the former movie mogul.

The defense dismissed the claims, saying all sex was consensual and at one point described the prosecutors opening arguments "as a preview to a movie we're not going to see," according to ABC News' Chris Francescani.

3. Ex-CEO: Grammys rigged

Former Grammys CEO Deborah Dugan is claiming that the Recording Academy "manipulates the nominations process," according to her complaint filed with the Equal Employment Opportunity Commission.

Dugan, who was put on leave last week for unspecified misconduct, also alleged in the complaint that she was subject to retaliation for accusing an academy executive of sexually harassing her. He has denied the claim.

"She's saying essentially she was sidelined from this position and the big bombshell that everyone is now talking about is that she's saying that the Recording Academy may have rigged nominations, voting and even who gets to perform at the Grammys," ABC News' Erielle Reshef tells the podcast.

In a statement, the Recording Academy accused Dugan of creating a "toxic and intolerable work environment and engaged in abusive and bullying conduct," allegations that Dugan has denied. The academy added that it "immediately launched independent investigations to review both Ms. Dugan’s potential misconduct and her subsequent allegations."

This baby’s spunky hairdo has everyone turning heads online.

Meet 10-week-old Anna Lattari from Long Island, New York, who is now affectionately known by her family as "Spike" or "Fluffy" for her full head of hair.

Her mother Lindsay Lattari said she was first tipped off to Anna's hair when she was still in the womb. Lattari’s doctor measured the baby's head and saw some extra headspace. "The doctor said, 'Anna’s head is measuring bigger, that usually means the baby has a lot of hair!'" Lattari told "Good Morning America."
