Their relationship has become considerably more amicable.
Biden has praised Harris publicly many times and noted that he’s thought highly of her personally and professionally since she became close to his late son, Beau Biden, when both were state attorneys general.
It is common for high-profile politicians to take notes with them to the podium, either handwritten additions to formal remarks or a bullet-point list.
The latter is like what Biden held on stationery featuring his full name: Joseph R. Biden Jr.
In March, early in the coronavirus pandemic, President Donald Trump's notes were photographed to show “Chinese” written over “corona,” part of the president's efforts to blame the pandemic on a foreign adversary.

Last year, as Trump faced impeachment for pressuring Ukraine officials to help his reelection by finding dirt on Biden, the president had notes that read: “I want nothing” and “I want no quid pro quo.”
Biden's list, at the least, suggests that he wants to defuse any tensions around his relationship with Kamala Harris.
As reflected in his notes, Kamala has become a reliable surrogate for Biden, appearing with him in online fundraisers amid the unusual social distancing standards forced on the campaign by the coronavirus pandemic.
As recently as last week, Harris headlined her own event for Joe.
One focused on the Raleigh area in North Carolina, a battleground state where Harris' dual appeal to Black voters and college-educated white women could boost Democrats' prospects.
Joe Biden ultimately did not field a question specifically about the former state attorney general.
A spokesperson for Kamala Harris did not immediately respond to a request for comment.
In just his third extended news conference in four months, Biden also sidestepped specific questions about the timing of his decision on a running mate, an approach reflected in another entry on Biden's notepad.
Under the heading “VP,” Biden wrote “highly qualified” and “diverse group,” signifying his intention not to tease out any more details.
