[Q]: Eric Hargan  is about to get a demotion  and  he  is just fine with that.
The acting secretary of the Department of Health and Human Services is more than thrilled to go back to the position  he  originally held. President Trump tapped him to lead the agency after Tom Price resigned when scrutiny of his travel habits revealed a taste for the excess.
Alex Azar is the president's new choice to run HHS.  Hargan  sat for this interview as Azar faced his first Senate confirmation hearing on Nov. 29.  Hargan  has held the position since early October  but this is certainly not  his  first rodeo at HHS. From 2003 to 2007   he  served here under then-President George W. Bush.
 Hargan  is a man grounded in  his  family's roots in Mound City  a small southern Illinois town just across the Ohio River from Kentucky where  his  parents not only advocated for a lifetime in public service but also led by example.
 He  said: "I grew up on a farm  my father held different local elected offices from county commissioner to school board  and my mother worked in a variety of healthcare roles throughout her life; first at St. Mary's hospital  which is no longer there  and then at the Cairo Community Health Clinic. All total  a career serving her community's healthcare that spanned 58 years."
 Hargan  faced reporters at the White House almost three weeks ago to discuss Trump's decision to donate his third-quarter salary to HHS in order to combat the opioid crisis.  Hargan  said the donation would be used for the planning and design of a large-scale public awareness campaign about opioid addiction.
" His  decision to donate  his  salary is a tribute to  his  compassion  to  his  patriotism and  his  sense of duty to the American people "  he  said.

[Q]: When  Ava Gardner  first met Frank Sinatra in 1943   the duo  couldn’t have suspected that six years later  after the actress faced two disastrous divorces before the age of 25  they would happily dive into a controversial love affair.
Sinatra may have still been married  but an insistent  Gardner  reportedly made the singer ask Nancy for a divorce. The mother of  his  three young children initially refused  but she eventually granted Sinatra a divorce in 1951. One week after  his  divorce was final  Sinatra married Gardner.
“I don’t think [Frank] wanted to hurt Nancy ” said Uzarowski. “But at the same time  I don’t think  he  went out of  his  way to hide [the affair]. They did get into quite a lot of trouble with the public. There were angry letters  hate mail coming in every week to the studio.
“She really liked  Ava  ” said Uzarowski. “She could have had a very bad attitude towards  Ava  because she basically stole her father away from her mother. She could have been resentful. But there was none of that… Tina and Nancy were both very friendly with  Ava .”
“The first time she met  Ava   when she was a little girl of 4 or 5   Ava  got down on her knees so she [could] have eye contact with her ” said Uzarowski. “And she really treated her with a lot of attention and a lot of warmth. That obviously really impressed her as a child. She still remembered that after all of these years.”
Still   Gardner  and Sinatra wouldn’t share a happily ever after. Their marriage was plagued by jealousy  fiery tempers and insecurity. They also publicly battled. The relationship was reportedly so tumultuous that  Gardner  had two abortions during their marriage  which she later publicly admitted.
According to Tina   Gardner  later wondered what the couple could have done differently.
The marriage lasted for less than two years. In 1953  MGM announced their separation. Then in 1957   Gardner  and Sinatra were divorced. However  they apparently never got over each other. There were even rumors of a possible reconciliation.
 Gardner  would move on and live a quiet life in London for more than 30 years  seeking salvation from the paparazzi.  She  never remarried.
One of Sinatra’s biggest tragedies would come in 1990 when  Gardner  died at age 67 of pneumonia.
“[Tina] said it was such a huge blow to  him  ” said Uzarowski. “ She  said  he  never got over it… It was such a huge shock to  him .  She  was the love of  his  life  by all accounts. When  she  did pass away   he  was devastated.
"Tina said the actual pain  he  experienced was so much more.  He  wouldn’t share that with anyone because it was too personal… There was a story that Nancy said in another book that  he  just locked  himself  in a room for 24 hours… and wouldn’t speak to anyone.”
