E-cigarette flavorings may pose heart risk, study finds

Chemicals used to flavor electronic cigarettes can damage cells that line blood vessels and may pose a risk to a user's heart in the long term, according to a study published Monday.

Why it matters: The study, published in the Journal of the American College of Cardiology, is the latest evidence that vaping may be harmful.

What they're saying: "Until now, we had no data about how these e-liquids affect human endothelial cells," said study co-author and Stanford Cardiovascular Institute director Joseph Wu.

"This study clearly shows that e-cigarettes are not a safe alternative to traditional cigarettes. When we exposed the cells to six different flavors of e-liquid with varying levels of nicotine, we saw significant damage. The cells were less viable in culture, and they began to exhibit multiple symptoms of dysfunction."

The other side: A January study found e-cigarettes are an effective way for smokers to quit smoking — twice as effective as other nicotine products like gum and patches.

President Trump tweeted on Thursday that he would endorse "any candidate" with a pulse who runs against Sen. Lisa Murkowski (R-Alaska).

Driving the news: Murkowski said on Thursday that she supported former defense secretary James Mattis' condemnation of Trump over his response to protests in the wake of George Floyd's killing. She described Mattis' statement as "true, honest, necessary and overdue," Politico's Andrew Desiderio reports.

Over the course of just a few hours, President Trump was rebuffed by the Secretary of Defense over his call for troops in the streets and accused by James Mattis, his former Pentagon chief, of trampling the Constitution for political gain.

Why it matters: Current and former leaders of the U.S. military are drawing a line over Trump's demand for a militarized response to the protests and unrest that have swept the country over the killing of George Floyd by police.

A New York Times spokesperson said in a statement Thursday that the paper will be changing its editorial board processes after a Wednesday op-ed by Sen. Tom Cotton (R-Ark.), which called for President Trump to "send in the troops" in order to quell violent protests, failed to meet its standards.

Why it matters: The shift comes after Times employees began a coordinated movement on social media on Wednesday and Thursday that argued that publishing the op-ed put black staff in danger. Cotton wrote that Trump should invoke the Insurrection Act in order to deploy the U.S. military against rioters that have overwhelmed police forces in cities across the country.
