Charlotte, North Carolina (CNN) A week after launching his presidential bid, Beto O'Rourke is poised to hire veteran Democratic strategist Jen O'Malley Dillon to lead his campaign, officials familiar with the discussions told CNN, a move that puts a former top aide to President Barack Obama at the helm of the O'Rourke campaign.

O'Malley Dillon, a deputy campaign manager for Obama's re-election effort in 2012, met with O'Rourke earlier this month in Texas before he jumped into the race. Since then, the campaign raised more than $6 million on its first day and the former congressman from Texas embarked on a tour of a half-dozen states.

O'Malley Dillon, who is seen as one of the party's sharpest data experts, had been planning to head a new data exchange operation for Democrats. The effort was designed to help the party overcome its deficit with Republicans on using voter data to identify supporters and drive turnout.
