Ms. Harris tapped former Attorney General Eric H. Holder Jr., who once oversaw Barack Obama’s vice-presidential vetting, to oversee her choice of a potential running mate, according to two people briefed on the matter.

Two of Ms. Harris’s top political advisers, Sheila Nix and Brian Fallon, joined the Monday morning call of senior staff members on the Biden-turned-Harris campaign — a sign of her team’s widening footprint inside the operation.

The next step in the party’s formal nomination of Ms. Harris will come on Wednesday, when the rules committee of the Democratic National Convention is scheduled to meet to set a date for a virtual roll-call vote of the state delegations.

Any momentum toward a competitive nominating contest appeared to melt away early Monday when a half-dozen Democratic governors quickly fell into line behind Ms. Harris — among them Andy Beshear of Kentucky, JB Pritzker of Illinois, Wes Moore of Maryland and Gretchen Whitmer of Michigan.

Democrats were delighted by the jolt of energy, with donors flocking to give after Mr. Biden’s exit: The Harris campaign announced on Monday that it had raised $81 million in her first 24 hours, a record sum, from 888,000 unique contributors.

Tim Walz of Minnesota was due for a round of cable TV interviews on Monday night and Tuesday morning, during which he planned to explain the party’s nominating process and promote his own political biography.
