Joe Biden was “not fit to run” and “is certainly not fit to serve” as president, his Republican rival Donald Trump said Sunday after the US leader said he was dropping out of the White House race.

“Crooked Joe Biden was not fit to run for President, and is certainly not fit to serve — And never was! … We will suffer greatly because of his presidency, but we will remedy the damage he has done very quickly. MAKE AMERICA GREAT AGAIN!” Trump posted on his Truth Social network shortly after Biden’s announcement.

‘No Distance Between The Two’

Biden has endorsed his vice Kamala Harris in the wake of his decision.

But Trump’s campaign team has lashed into Vice President Kamala Harris after Biden endorsed her to take his place atop the Democratic Party’s presidential ticket, saying she would be “even worse” than the outgoing leader.

“Harris will be even worse for the people of our nation than Joe Biden. Harris has been the Enabler in Chief for Crooked Joe this entire time.They own each other’s records,and there is no distance between the two,” the campaign said in a statement.

Meanwhile, the Democratic Party will hold a “transparent and orderly” process to pick a new nominee, the party chair said after Biden’s move.

“In the coming days, the party will undertake a transparent and orderly process to move forward as a united Democratic Party with a candidate who can defeat Donald Trump in November,” chair Jaime Harrison said in a statement praising Biden. (AFP)
