President Trump dismissed reports that his campaign is “running low on money” early Tuesday morning, vowing to spend personal funds on his reelection bid if necessary.

“I keep reading Fake News stories that my campaign is running low on money. Not true, & if it were so, I would put up money myself. The fact is that we have much more money than we had 4 years ago, where we spent much less money than Crooked Hillary, and still easily won,” Trump tweeted, referring to former Democratic presidential nominee Hillary Clinton.

“Much of the money we have spent is on our ground game, said to be the best ever put together. I’ll let you know how good it is on November 3rd. Very expensive to do, but opportunity could be BIG! I will spend additional money if we are not spending enough!” he continued.
