Start Here: Trump and Biden in Iowa, Kim Jong Nams CIA ties, Jon Stewarts rage

It’s Wednesday, June 12, 2019. Let’s start here.

1. ‘Someone who can beat Donald Trump’

Former Vice President Joe Biden and President Donald Trump held each held rallies in Iowa on Tuesday, giving voters an early preview of a potential 2020 matchup.

Biden is leading fellow Dems in the polls, but with 22 others running, ABC News Senior Congressional Correspondent Mary Bruce tells “Start Here” that some Democratic voters aren’t sold on him as the front-runner.

“Speaking with voters out here,” Bruce reports from Mount Pleasant, Iowa, “there are a lot who still have not made up their mind. Many say they simply are looking for someone who has stability and someone who can beat Donald Trump.”

2. Spooky

Kim Jong Un’s assassinated half-brother, Kim Jong Nam, had become an informant for the CIA and met with operatives on several occasions before he was killed two years ago in Malaysia, according to the new book “The Great Successor” by Anna Fifield, Beijing bureau chief for the Washington Post.

“Everyone points the finger at Kim Jong Un — why did he kill his half brother?” ABC News Chief Global Affairs Correspondent Martha Raddatz says. “If this is in fact true, and he was speaking to the CIA, it would explain quite a few things about why he was offed.”

ABC News has not independently confirmed the claim. The CIA declined to comment.

3. Stewart to Congress: Do your job!

Jon Stewart blasted Congress in emotional testimony on Capitol Hill as he called on lawmakers to fully fund a program to help 9/11 first responders.

“They responded in five seconds,” Stewart said. “They did their jobs — with courage, grace, tenacity, humility. Eighteen years later, do yours!”

The September 11th Victim Compensation Fund is set to run out of money in 2020, and Stewart, who has long advocated for the first responders, wants lawmakers to approve permanent funding, according to ABC News’ Ben Siegel.

“For many people, especially in the House, this is a no-brainer, but we’re expecting some resistance in the Senate, where things get a bit more caught up in the politics as well as the pricetags,” Siegel tells us.

The House Judiciary Committee is set to vote on the program’s funding today.

4. Russian reporter released

An investigative journalist was released by Russian authorities amid mounting pressure over his detention a week after he was arrested on drug charges.

Police claimed Ivan Golunov, a reporter for the independent news site, Meduza, had bags of mephedrone and released photos that suggested Golunov had an at-home drug lab. Golunov argued that the drugs were planted on him and that the photos were fabricated.

Hundreds of protesters had participated in demonstrations calling for Golunov’s release. On Tuesday, Interior Minister Vladimir Kolokoltsev announced the case was being closed after an analysis found no proof of his alleged crimes.

“What the story shows,” ABC News’ Patrick Reevell reports from Moscow, “is how Russian authorities have been pushed to do something that they didn’t want to do by protests.”
