White House Engages Liberal Activists in Battle to Fill Scalia's Seat

The White House held a conference call with liberal activist groups Tuesday.

"From our perspective as an advocacy organization, it is remarkable how instantly so many groups have expressed so much interest and anxiety about what’s going to happen with this vacancy,” Barry said.

With the political leaning of the court hanging in the balance now that Scalia's seat has been vacated, interest groups invested in a wide array of issues -- ranging from immigration to gun rights to health care and beyond -- have a stake in the outcome of the pending nomination battle.

The New York Times first reported the news of the White House conference call today.

One participant who spoke to ABC News disputed the characterization of the call, as described by another participant to the Times, as a "part pep rally" and instead described it as as a briefing call to engage a broader group of stakeholders and provide talking points to rebut anticipated GOP rhetoric -- but not to proactively condemn Republican opponents.

The White House had no comment when asked about the call by ABC News.
