Washington (CNN) - White House officials are reaching out to some Democratic senators to discuss the possible nomination of Janet Yellen to head the Federal Reserve, one source with knowledge of the calls confirmed to CNN.
The only name mentioned on these calls is that of Yellen, the source told CNN, adding the idea is to generate support for the expected nomination.
"It is to generally be positive on the idea," the source said.
White House officials have not discussed a time frame with the senators, according to this source. However, it is believed the outreach signals the nomination will be announced soon.
The source refused to speak on the record because the calls, which have been ongoing for several days, are private.
If nominated Yellen would succeed Ben Bernanke as chairman of the Federal Reserve. She became the leading contender after former White House economics adviser Larry Summers withdrew his name from consideration on Sunday because of building opposition by Democrats in the Senate.
When asked Friday whether President Obama will announce his pick to be the next Fed chairman next week, White House Deputy Press Secretary Josh Earnest said, "I don't have any updated timing for you in terms of any personnel announcements, let alone the personnel announcements that many people are legitimately and understandably interested in."
The White House would not comment on the outreach efforts.
The Wall Street Journal first reported the White House outreach.
