Democratic Party officials have argued that the virtual vote to select the presidential candidate must take place by August 7 to avoid the risk of litigation in Ohio.
But when and how should the running mate who appears on the ballot alongside the candidate be chosen?
It's a key issue that members of the Democratic National Committee's Rules and Bylaws Committee plan to address when they meet on Wednesday, two members told CNN.
The co-chairs of the Democratic National Committee's rules committee have not yet finalized a formal agenda for the meeting, which will be streamed online, according to two of the people.
Choosing a running mate for the party's front-runner, Vice President Kamala Harris, with the convention just four weeks away would mean accelerating a vetting process that typically takes months. Choosing a running mate before the roll call deadline on Aug. 7 would require an even faster process.
CNN reported that Attorney General Eric Holder and his law firm Covington & Burling are handling the vetting process for Harris as a running mate.
In 2020, when Democrats adopted a remote voting process similar to the one they are proposing this year, Democratic nominee Biden essentially only had to nominate his running mate, avoiding the need for a separate vote to certify the selection.
