Jo Ann Emerson

In August 2015, Emerson took a leave of absence from the NRECA for medical reasons and was succeeded by her former congressional chief of staff and chief operating officer, Jeffrey Connor, in an interim capacity in November, effectively stepping down. In June 2016, former U.S. Representative Jim Matheson was named to succeed Emerson as CEO and took over her post in July. In March 2017, Emerson received the Clyde T. Ellis Award, the highest honor bestowed on an individual by America's electric cooperatives. On her behalf, her husband, Ron Gladney, accepted the award.

Sometime after leaving the NRECA in 2015, Emerson suffered a stroke while on a family vacation to Italy which left her paralyzed from the neck down. In 2020, while living in the Knollwood retirement community in Washington, D.C., she tested positive for coronavirus disease 2019 (COVID-19) amid the eponymous pandemic. She later tested negative.

Emerson announced in early December 2012 her plans to retire from Congress in February 2013 to assume a position with the National Rural Electric Cooperative Association (NRECA) as its president and Chief Executive Officer.

With the defeat of Congressman Ike Skelton, Emerson became the dean, i.e., the longest-serving member, of Missouri's congressional delegation in 2011.

On September 15, 2009, Emerson was one of seven House Republicans to vote in favor of the Democrats' proposed resolution to condemn U.S. Representative Joe Wilson (R-South Carolina) for shouting "You lie!" in the middle of President Barack Obama's joint address to the U.S. Congress on health care reform.

On July 12, 2007, Emerson was one of only four Republicans in the U.S. House of Representatives who voted to withdraw U.S. troops from Iraq by April 2008.

On May 24, 2005, Emerson was one of 50 Republicans to vote in favor of overturning President George W. Bush's ban on federal funding for embryonic stem cell research. She cast her "yea" vote the day after her mother-in-law died from Alzheimer's Disease, one of the illnesses for which scientists believe they can create better treatments from stem cell research.

Following Bill's death, Jo Ann married Ron Gladney in 2000. From this marriage she gained two stepdaughters and a stepson.

When her husband Bill died in 1996, Jo Ann announced she would run for his vacant seat. However, Missouri state law prohibited her from filing in the Republican primary for the general election. In November, Jo Ann Emerson competed in two elections on the same day. She ran as a Republican against Democrat Emily Firebaugh in the special election to finish the last two months of her late husband's eighth term, and as an independent against Democrat Firebaugh and Republican Richard Kline in the general election for a full two-year term. She won both elections easily and has been reelected seven times without serious difficulty. She is the first Republican woman elected to the U.S. Congress from Missouri. She served the last two months of her husband's term as a Republican, then as an independent caucusing with the Republicans before officially becoming a Republican again at the onset of the new Congress in 1997. She was briefly the first independent elected to federal office in Missouri in 122 years and is the first, and so far only, woman to be elected and serve in Congress as an independent or third party member.

Hermann married future U.S. Representative Bill Emerson, a Republican from Cape Girardeau, on June 22, 1975. They had two daughters; Jo Ann also has five stepdaughters and a stepson. Bill was elected to the U.S. Congress in 1980 from Missouri's 10th Congressional District and, subsequent to redistricting, was reelected in 1982 from the 8th District. He died from cancer on June 22, 1996, a few months before the end of his eighth term. The Bill Emerson Memorial Bridge, which links Missouri to Illinois across the Mississippi River, was dedicated to commemorate his efforts to obtain federal funding for its construction.

On January 22, 2013, Emerson resigned her seat in Congress to become the President and Chief Executive Officer of the National Rural Electric Cooperative Association. She served as CEO until August 2015.
