Republican senators shrugged off the potential ramifications of Donald Trump’s fundraising deficit Tuesday and laughed about the possibility of the businessman self-funding his campaign as promised.

“It’s up to him to decide [whether to self-fund], it’s his money,” Marco Rubio of Florida told THE WEEKLY STANDARD in the Capitol. Rubio acknowledged that Trump’s finances were in a sorry state, with less than $1.3 million cash on hand at the start of June compared to Hillary Clinton’s $42 million.
