<p>REHOBOTH BEACH, Del. — President Joe Biden helped his wife celebrate her 70th birthday on Thursday with a leisurely bike ride.</p>
<p>The president and Jill Biden — with a few Secret Service agents in tow — cycled the paved Cape Henlopen State Park trail near their Delaware beach home.</p>
<p>Well-wishers hooted and greeted the first lady with cheers and birthday greetings as the couple arrived at the trailhead near Gordons Pond beach. A smaller group sang “Happy Birthday" to her as she and the president finished up their ride on the 5.2-mile (8.4-kilometer) trail.</p>
<p>Jill Biden smiled and shouted, “Thanks!” as she and the president pedaled on toward their nearby house.</p>
<p>The president joined his wife at their beach house Wednesday evening to mark what a spokesperson for the first lady, Michael LaRosa, said would be a “quiet” birthday at their beach home. No family or friends were expected to join them.</p>
<p>The trip was a rare midweek getaway from the White House by a president. It also was Biden’s first visit to the couple’s vacation home since he took office in January. </p>
<p>The president is expected back at the White House on Friday. </p>
<p>Jill Biden, a longtime community college English professor, recently finished virtually teaching a course at Northern Virginia Community College. She won’t be teaching over the summer.</p>
