Former President Barack Obama appeared at a campaign event Oct. 19 for the first time since leaving office.
Obama spoke at an invite-only gathering in New Jersey to promote the gubernatorial campaign of Democrat Phil Murphy, reports Time magazine.
The former commander in chief did not refer to the current occupant of the White House by name, or name any member of Congress.
"Some of the politics we see now we thought we'd put that to bed," Obama said. "That's folks looking 50 years back. It's the 21st century not the 19th century."
He also did not address President Donald Trump's incorrect statement that Obama, during his time in office, never called military family members after a relative was killed while serving.
Obama instead focused on what had to be done to bring about change.
"You cannot complain if you didn't vote; you did not exercise the power the Constitution gives us that people fought for," Obama said. "This is entirely under your control. If you don't like how things are going, you gotta vote."
Murphy is expected to win the Nov. 7 election. Current Republican Gov. Chris Christie's term limit has expired.
"You can't take this election or any election for granted -- I don't know if you all noticed that," Obama added, according to NBC News.
Trump has undermined several key parts of Obama's legacy in recent weeks, including the Iran nuclear deal, the health care system and immigration policy, CNN reported.
An adviser to the former president stressed that Obama has no intention of becoming engaged in a campaign against the Trump administration.
"It's in no one's interest -- including the former president's, the Democratic Party's, or the country's -- for President Obama to become the face of any resistance or the party," the adviser said, Time reported. "Instead, he is creating the space for leaders in the party to craft the best path forward that will make our country better."
Later on Oct. 19, Obama will travel to Virginia to support the campaign of the Democratic gubernatorial candidate Ralph Northam.
"Barack Obama coming into Virginia tonight is just very exciting, and he's gonna energize our voters and just kind of close that loop for us," Northam said, according to NBC News.
Northam is in a close race with his Republican challenger, Ed Gillespie.
Other senior figures from the Obama administration have also returned to the campaign trail, including former Vice President Joe Biden, who has campaigned for Northam and Murphy. In addition, former Attorney General Eric Holder has traveled to Virginia.
