The Republican National Committee and some of the most prominent black Republican politicians will hold an event commemorating the 50th anniversary of the March on Washington later this month.

According to an invitation obtained by Post Politics, RNC Chairman Reince Priebus will be joined by Sen. Tim Scott (R-S.C.), former congressman Allen West (R-Fla.), former Ohio secretary of state Ken Blackwell and Elbert Guillory,  the black Louisiana state senator who recently switched parties. Also invited are Rep. James Sensenbrenner (R-Wis.) and James Kemp, the son of former congressman Jack Kemp.

Lesser-known black Republicans who will take part include Oklahoma state House speaker T.W. Shannon and RNC members Ada Fisher (North Carolina), Glenn McCall (South Carolina) and Robin Armstrong (Texas).

The luncheon event will take place Aug. 26 at the Capitol Hill Club; it is not a fundraiser.

The 1963 March on Washington is where Martin Luther King delivered his "I Have a Dream" speech.

Priebus has made a deliberate effort to make inroads in the black and Hispanic communities, arguing that the party needs to expand its appeal to minority voters.

Correction: This post incorrectly referred to James Kemp as Jack Kemp. The elder Kemp died in 2009.
