With Lisa Song and Elizabeth McGowan, he won the 2013 Pulitzer Prize for National Reporting,[1] and a 2016 Robert F. Kennedy Journalism Award.

[4] Hasemyer was exposed as an alleged child predator by People v. Preds as catch #129, stemming from inappropriate messages to a 14 year-old male decoy in February 2022.

I worked a while and then called him again; this time he said he'd talk, but only with the Union there, too.Hasemyer continued to cover the events leading up to Dominelli being taken into custody by U.S.

[7][13] Hasemyer also served as an on-call public information officer, (strategy and messaging specialist) with FEMA, and participated in the response to Hurricane Sandy in New York.

In the cover letter for entry to the prize, dilbit is described as "a thick Canadian hydrocarbon called bitumen that is diluted with liquid chemicals so that it can flow through pipes".

[1] The pipeline already had corrosion problems and it was more than a week before the EPA knew that they were dealing with dilbit, because the pipeline operators weren't required to tell first responders in the event of a spill; dilbit is different from normal oil, in that the chemicals evaporate and the thick, different form of oil, sinks to the bottom and is very difficult to clean up.

[26] According to the cover letter, in the entry for the prize, the investigations stemmed from research that Lisa Song had originally began, and McGowan and Hasemyer joined in shortly after.

After conducting dozens of interviews and examining company memos from as far back as the 1970s, and hundreds of internal documents, InsideCimate published a series of 9-stories, "Exxon: The Road Not Taken".

The publication of the series, resulted in the Attorney General of New York, issuing a subpoena to Exxon, in order to look into the possibility of fraud.

[40] They received the following awards for the same series: For the past 20 years Exxon has worked to discredit climate science.

As of 2020, ExxonMobil still denies any wrongdoing in voicing their opinion on climate policy, claiming that activist organizations are seeking to punish the company, and coordinating an attack campaign on social media, using the hashtag #ExxonKnew.
