From this morning's Earlybird:

• "President Obama will nominate Solicitor General Elena Kagan as the nation's 112th justice, choosing his own chief advocate before the Supreme Court to join it in ruling on cases critical to his view of the country's future, Democrats close to the White House said Sunday," the New York Times reports.

• "Democrats are looking to the bipartisan Senate support" Kagan "secured for solicitor general last year as an indicator of how she might fare as a Supreme Court nominee. But Republicans are saying, not so fast," Roll Call (subscription) reports.

• The New York Times profiles Kagan.

• The Wall Street Journal (subscription) republishes the questionnaire Kagan filled out to become solicitor general.
