Yesterday’s debt-limit talks were “very constructive,” according to President Obama. But with party leaders still far apart on a number of issues, Obama will reconvene the group Sunday in hopes of reaching a deal before the administration’s Aug. 2 deadline. Rank-and-file lawmakers are growing impatient with the pace of progress.

This weekend also marks the Republic of South Sudan’s declaration of independence ceremony. Obama announced an American delegation to mark the occasion. U.N. Ambassador Susan Rice will lead the group, which also includes former Secretary of State Colin L. Powell.

Today on Capitol Hill, meanwhile, the House Ways and Means Committee will hear testimony on the impact of Social Security changes. The hearing will focus on Social Security’s finances, particularly the current benefit expenditures and proposed changes to those expenditures.
