Good morning, I'm Taylor Wilson and this is five things you need to know Thursday, the 20th of July, 2023.

Today, IRS whistleblowers speak out about Hunter Biden,

plus the president of Stanford steps down after problems were found in his research.

And we look at how extreme heat in Alaska is impacting national security.

Two IRS whistleblowers gave Congress their side of the story yesterday from a year's long investigation into Hunter Biden.

Speaking out of joint hearing, internal revenue service employees Greg Shapley and Joseph Ziegler alleged that just as department officials slow walked their investigation into the president's youngest son.

Ziegler said quote, it appeared to me based on what I experienced that the US attorney in Delaware and our investigation was constantly hamstrung, limited and marginalized by officials, as well as other US attorneys.

It was the first public testimony from the two IRS agents assigned to the case, which focused on gun and tax charges against Hunter Biden.

He ultimately pled guilty to two misdemeanor accounts of tax evasion and agreed to participate in a pretrial program in June.

The president of Stanford University announced his resignation yesterday set for the end of August.

Mark Tessier Levine stepping down comes after the school's board of trustees launched a review in December following allegations that he engaged in fraud and other unethical conduct related to research and papers that were up to two decades old.

Panelists found multiple cases of manipulated data in the papers they investigated.

They found that Tessier Levine, who's a neuroscientist, was not responsible for the misconduct.

But that he was the principal author in several papers where there was a parent manipulation.

He said he's quote, never submitted a scientific paper without firmly believing that the data were correct and accurately presented on quote.

But he said that he should have been more diligent in seeking corrections for his work and should have had tighter controls in his laboratory.

Extreme heat from climate change is baking Alaska.

And that's creating a host of national security problems.

I spoke with USA Today Pentagon correspondent Tom Vandenbrook to learn more.

Thanks for hopping on Tom. Good to be your Taylor.

Since Tom's starting here, how exactly is climate change impacting the Alaska Arctic?

In the number of ways Taylor, one of the principal ways most immediately is rising sea levels have damaged coastal radar sites in Alaska.
