WATCH: Joe Biden ridicules Donald Trump for non-serious campaigning

Former US president Donald Trump came under fire by incumbent President Joe Biden in a video for non-serious behaviour as he played golf and boasted achievements in the game instead of campaigning on the ground Thursday.

The video released on X — former Twitter — showed two of them in a single screen in which Joe Biden is in the campaign events while Donald Trump is busy taking shots at his golf club in Florida.

In the post, the 81-year-old Biden said: "I’ll tell you this: There’s a difference between the two candidates in this election."

According to the video, the Democrat visited eight swing states in March after addressing the last State of the Union. On the other hand, the 77-year-old Trump is busy playing the game.

The video also shows Biden taking pictures with his supporters, addressing people during rallies while Trump is driving a golf cart.

Later on, the video also presented a screenshot of Biden’s sarcastic congratulations to the business mogul who wrote on his Truth Social platform that he won two golf trophies at his own golf club’s awards.

In response, Biden wrote: "Congratulations, Donald. Quite the accomplishment."

Former president Trump is enmeshed in his legal troubles facing four criminal indictments and 91 counts of felonies. Recently, he received relief as an appeals court in New York reduced his bond money from $464 million to $175 million, with an extension of ten days.

The actor-turned-politician is also scheduled to hold a rally of supporters on April 2 in Wisconsin marking the second since other party contenders dropped out of the race.

The Democrat is currently busy in New York where he is to hold an extravagant fundraiser with two former presidents Barack Obama and Bill Clinton.
