"He has not been loyal to some of the people who were there for him from day one," Hartman, who fund raised for Obama's presidential campaign said during the scathing Q&A.
Hartman, who supported Obama as far back as 1995, when he ran for state senate, told the magazine that she feels "insulted" that she hasn't been invited to the White House.
"There's a whole backroom, black community story on Barack that the white media hasn't paid attention to. Barack was not launched by Penny Pritzker for the presidency. Barack was launched by black businesspeople. I call them the "Day One people." We've not been to the White House; we've not had appointments. I have barked a little bit about it.
Hartman told the magazine she was instrumental in convincing Al Sharpton to switch allegiances from Hillary Clinton to Obama during the presidential campaign.
In contrast, Hartman praises Mayor-Elect Rahm Emanuel as someone who's "appreciative" and "thankful" toward those who've helped him.
