Democrats continue their efforts to challenge president-elect Donald Trump's legitimacy.

Representative John Lewis (D-GA) started off the week telling "Meet the Press" host Chuck Todd he did not see Trump as a "legitimate president."

In response, Trump Tweeted that Lewis should be "helping and fixing" his district and that he was "All talk, talk, talk - no action or results. Sad!"

Trump's comments resulted in a backlash from Lewis and his supporters.

Lewis took advantage of the situation by fundraising off of Trump's comments and has vowed not to attend this week's inauguration along with other Democrat lawmakers.
