'Start Here': Trump asks Ukraine and China for Biden probe, Vegas has settlement, N. Korea talks

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

It's Friday, Oct. 4, 2019. Let's start here.

"I would think that if they were honest about it, they would start a major investigation into the Bidens," Trump said of Ukraine, adding, "China should start an investigation into the Bidens. Because what happened in China is just about as bad as what happened with Ukraine."

ABC News White House correspondent Karen Travers tells “Start Here” that the White House has still not refuted any specifics within the whistleblower complaint about Trump’s July 25 call with Ukrainian President Volodymyr Zelenskiy.

2. Shooting settlement

A settlement of up to $800 million to resolve claims against MGM Resorts stemming from the 2017 Las Vegas massacre was announced on Thursday.

“Our goal has always been to resolve these matters so our community and the victims and their families can move forward in the healing process," Jim Murren, chairman and CEO of MGM Resorts, said in a statement.

Robert Eglet, a lead counsel for the victims of the massacre and their families, said the agreement "marks a milestone in the recovery process" for the victims.

"While nothing will be able to bring back the lives lost or undo the horrors so many suffered on that day, this settlement will provide fair compensation for thousands of victims and their families," Eglet said in a statement.

Under the settlement agreement, the victims have agreed to dismiss all pending litigation against MGM Resorts, according to the company's statement.

ABC News Chief National correspondent Matt Gutman tells “Start Here” that some victims say MGM “stepped up to the plate” with this settlement.

3. New North Korea talks

Talks between the U.S. and North Korea are set to resume today after the failed Hanoi summit between the two nations and a series of North Korean rocket launches have heightened tensions between the two sides.

ABC News Chief Global Affairs correspondent Martha Raddatz tells the podcast that the recent launches are a way for Kim Jong Un to remind the U.S. of what they’re capable of.

4. DIY rape kit warning

Connecticut on Thursday became the latest state to question the manufacturers of do-it-yourself rape kits over their representation that their products will yield evidence admissible in court.

Brooklyn-based “MeToo Kit” and New Jersey-based PRESERVEkit have offered products for women to self-collect evidence of a sexual assault instead of relying on an invasive hospital examination.

Connecticut has now joined several other states in notifying the manufacturers their products may violate fair trade laws.

Connecticut District Attorney William Tong tells “Start Here” that he believes the kits “do much more harm than good” and that women should approach authorities to be tested by professionals.

“The fact is that 77% of sexual assault survivors do not report the crime,” Jane Mason, co-founder of PRESERVEkit, posted to her website. “The PRESERVEkit exists for the 77%.”
