Former President Donald Trump was apparently watching Vice President Kamala Harris’ speech at the Democrats’ nominating convention, and he had some thoughts.

In a post on Truth Social, Trump asked, “WHERE’S HUNTER?”

His comment appeared to refer to Hunter Biden, President Joe Biden’s son, who is not related to Harris.

Check out some of the other reactions below:

During her speech, Harris labeled Trump an “unserious man.”

She shared an upbeat message about the future of the country, saying, “With this election, our nation has a precious, fleeting opportunity to move past the bitterness, cynicism, and divisive battles of the past. A chance to chart a new way forward — not as members of any one party or faction, but as Americans.”
