CNN correspondent Jim Acosta asked White House press secretary Sarah Sanders on Monday if President Trump's praise for NASCAR that morning had anything to do with race, noting most fans of the organization are white.

"Why is it that the president over the weekend is going after or seeming to go after African-American athletes?" Acosta said, referring to Trump's recent attacks on the NFL after players have protested racial injustice by kneeling during the national anthem before their games. "And then this morning he's putting out a tweet praising NASCAR, which obviously is geared towards a different demographic, and the way they stand and respect and honor the flag. Is he trying to wage something of a culture war?"

Trump had praised NASCAR over Twitter earlier in the day. "So proud of NASCAR and its supporters and fans," he said. "They won't put up with disrespecting our Country or our Flag - they said it loud and clear!"

The tweet was possibly triggered by a report that aired on Fox News Monday morning about NASCAR owners warning their players against engaging in similar protest dispalys.

Sanders told Acosta that Trump's comments about the NFL and NASCAR were not about race but "about pride in our country."
