(CNN) President Donald Trump is under fire again, this time for his firing of former FBI Director James Comey. But many of his supporters aren't joining the outcry. CNN spoke to Trump backers across the country, and while some of them expressed surprise at Comey's ouster, few said it changed their image of the leader of the free world. Here's what they had to say: Jake Lee, business owner Lee, 46, of West Hollywood, California, said he believes Trump made "the right decision" in axing Comey. "As far as the Comey thing goes, I think he gave him plenty of chances. I think what became the last straw was when he (Comey) made that statement about the classified emails showing up on (Hillary Clinton aide Huma Abedin's and her husband, former Congressman Anthony Weiner's) laptop. You can't have rules for the elitist ruling class and not have those rules apply to everybody else. I think in my opinion that was part of (Trump's) decision. The guy likes to run a tight ship."Many Trump voters across the country say James Comey's firing doesn't change their opinion of the President"I was hoping Trump would've done a lot better with his presidency so far," Kentucky business owner says 
 Question:He also appreciated the unexpected nature of _'s announcement: "Trump doesn't broadcast what he's gonna do; he just does it, and I like that."
Donald Trump

Havana (CNN) U.S. President Barack Obama put the authoritarian government in Havana on the spot Monday, taking questions from reporters and insisting that his Cuban counterpart also deliver answers to pointed queries on human rights, political prisoners and economic reforms. Though they both acknowledged deep disagreements on these issues, the two leaders found common ground on the topic of the economic embargo on Cuba, which both want lifted. Obama went so far as to declare that "the embargo's going to end," though he couldn't say when. In an extraordinary sign of the shifting attitudes, Castro was willing to answer one question on why his regime was keeping Cubans incarcerated for expressing anti-government views. But his response only underscored the schisms between himself and Obama.President Barack Obama and Cuban leader Raul Castro shook hands at the Palace of the Revolution in Old Havana on MondayScores of anti-Castro dissidents from the group Ladies in White were arrested over the weekend and detained after their weekly protest"¿Que bolá Cuba?" the U.S. President wrote on Twitter on Sunday, using an informal Cuban greeting

(CNN) Your "BPA-free" plastic product may be no safer than the product it replaced, says a new UCLA study that analyzed the impact of a common BPA alternative on zebra fish embryos. The study joins a small but growing group of similar research sounding the alarm about so called "BPA-free" alternatives. "Our findings are frightening and important," said senior author and reproductive endocrinologist Nancy Wayne. "Consider it the aquatic version of the canary in the coal mine." After decades of animal research linked BPA (Bisphenol A), a known endocrine disruptor, to problems with brain and reproductive development, early puberty and a rise in breast and prostate cancer, many manufacturers stopped using the chemical to harden plastics, replacing it with "BPA-free" alternatives. The most common replacement is BPS (Bisphenol S), said Wayne.BPA-free alternatives may be no safer than BPA, say researchersMost common alternative, BPS, linked in study to disruptions of estrogen and thyroid hormones 
 Question:Another study, this time in rats, found _ caused heart arrhythmia when given in doses equivalent to those humans usually experience.
