Liz Cheney is dropping out of Wyoming's Senate primary.
The official announcement from Cheney – the eldest daughter of former Vice President Dick Cheney – came early Monday.
In an official statement released by her campaign,the eldest daughter of former Vice President Dick Cheney said the health of her family was "her overriding priority."
"Serious health issues have recently arisen in our family, and under the circumstances, I have decided to discontinue my campaign," the statement said.
"My children and their futures were the motivation for our campaign and their health and well being will always be my overriding priority. Phil and I want to thank the thousands of people in Wyoming and all across the country who have supported my campaign.
Her Wyoming credentials were challenged in spite of her family's deep roots in the state, because she spent much of her youth and adult life in Virginia.
She had been trying to unseat Sen. Mike Enzi.
