Former President Barack Obama will host a reception for freshman House Democrats on Monday evening at the home of Ambassador Esther Coopersmith in Washington, D.C, Jewish Insider has learned. Coopersmith, known as “one of the best at playing the Washington ‘networking’ game,” was appointed by Obama as a UNESCO Goodwill Ambassador in 2009.

On Monday night, AIPAC will also hold its leadership reception, perhaps AIPAC’s most-significant annual gathering, which typically puts the vast majority of members of Congress, AIPAC’s leadership, board and national council all in one room, during the same block of time.

Several progressive 2020 presidential hopefuls, including Senators Elizabeth Warren and Kamala Harris, have already announced they won’t be attending AIPAC’s policy conference this year. However, NYC Mayor Bill de Blasio is scheduled to speak at the conference on Monday.

On any given night in D.C. while Congress is in session, members typically attend several receptions, but this conspicuous scheduling conflict has caught the attention of D.C. insiders. Obama’s reception is called for 7:15PM, while the AIPAC gathering is from 6:45PM until 10PM.
