AZ's US Sen. Mark Kelly being vetted for vice president by Kamala Harris campaign

U.S. Sen. Mark Kelly is among seven people asked to submit personal information as part of the vice-presidential vetting process, making clear he is under serious consideration for joining the Democratic ticket.

USA Today reported Tuesday that Kelly, D-Ariz., is part of a list that includes North Carolina Gov. Roy Cooper, Michigan Gov. Gretchen Whitmer, Pennsylvania Gov. Josh Shapiro, Minnesota Gov. Tim Walz and Illinois Gov. J.B. Pritzker.

All those people have been widely believed to be in the running for the position since Vice President Kamala Harris became the favorite to head a revamped Democratic ticket.

USA TODAY, citing an undisclosed source familiar with the vetting process, said Harris’ campaign is also considering former Rep. Cedric Richmond of Louisiana who served as a top aide in the Biden White House and on his campaign.

CNN reported that potential candidates are asked to submit information about their finances, family histories and other personal details.

Kelly had been a staunch supporter of President Joe Biden’s reelection bid and voiced support for the Biden-Harris ticket as late as last week.

He has been in the United Kingdom as part of a previously scheduled congressional trip since Biden ended his campaign and quickly backed Harris on Sunday but not commented on his potential inclusion on the new Democratic slate.

The Senate reconvenes on Tuesday.
