Now, some will see reinforcement of that idea as the commander in waiting, Vice President Kamala Harris is taking command of a key presidential duty.
Harris has taken on the usual presidential position of calling heads of state.
Harris talked with French President Emmanuel Macron on Monday, according to a White House readout that did not name President Biden, through the report.
Although Biden, 78, did talk with Macron on Jan. 24, it is unusual for a president to step aside for vice presidents to make the calls with world leaders.
"Vice President Kamala Harris has begun to take calls on behalf of President Joe Biden, raising questions about his ability to do the job of president," The National Pulse published. "It is bizarre for a vice president to be making contact with key world leaders just weeks into a new administration."
As the White House readout describes, Harris "expressed her commitment to strengthening bilateral ties between the United States and France and to revitalizing the transatlantic alliance." Also, Harris and Macron "agreed on the need for close bilateral and multilateral cooperation to address COVID-19, climate change, and support democracy at home and around the world," they further "discussed numerous regional challenges, including those in the Middle East and Africa, and the need to confront them together."
The vice president further wrote in a Twitter post: "Today I spoke with President @EmmanuelMacron of France. We discussed COVID-19, climate change, supporting democracy at home and around the world, and regional challenges. @POTUS and I look forward to working with President Macron to build a better future for our two countries."
Harris likewise made a call to Canadian Prime Minister Justin Trudeau this month, after Biden spoke with him on Jan. 22, according to the Times.
Though it seems like Biden is still refusing to speak with the Prime Minister of Israel, Benjamin Netanyahu, just yet.
"The prime minister congratulated the vice president on her historic election, and she recalled fondly her years spent in Montréal," Trudeau's office announced.
Biden started his tenure as the oldest president in U.S. history.
And critics are seizing on Harris' newfound value, especially after former Vice President Mike Pence did not have the same weight on making calls with world leaders.
Some have also noted how Harris may be setting up to lead the U.S. delegation at the G8 in June, especially if Biden is still busy playing Mario Kart.
