Lisa Ling to Caitlyn Jenner: Walk in Those Heels Longer Before You Shade Hillary Clinton

Lisa Ling is taking a huge shot at Caitlyn Jenner for shading presidential candidate Hillary Clinton.

We asked Lisa, a staunch Hillary supporter, about Caitlyn's comment on her show ... that Hillary cares more about herself than other women.

Caitlyn got all political during the season 2 premiere of "I Am Cait" -- but Lisa thinks Jenner needs to step out of the political arena ... at least where Hillary's concerned.

Watch ... she doesn't just throw shade, she attacks Caitlyn's womanhood.
