WASHINGTON — After the Republican National Convention pulled out of Charlotte earlier this year due to COVID-19 restrictions, the host committee pledged to give more than $3 million to local community groups by the fall. But a recent filing with the Federal Election Commission shows the committee has handed out less than $400,000 in cash so far, and the vast majority of the money leaders plan to dole out has yet to come in the form of grants reserved for unnamed economic development organizations.
