President Joe Biden signed an executive order on Thursday to improve cybersecurity around the country in an effort to protect the privacy of users and help shield them from cyberattacks.

Biden conveyed his deep appreciation for first lady Jill Biden, who joined him in the Oval Office. “My deepest appreciation to our amazing first lady with me in the Oval today, for our entire family, you’re the love of my life and the lives of my love,” he said. “My eternal thanks to you, the American people.”

After four years in the White House – and a half-century in Washington – President Joe Biden has said farewell.
