President Donald Trump’s re-election campaign boosted its spending in June amid an enormous cash influx and as the presidential race intensified, while former Vice President Joe Biden spent considerably less amid his advantages in polls.

The Trump campaign spent more than $50 million last month, about twice the amount of May, Reuters reported, citing a disclosure filed with the Federal Election Commission on Monday, July 20.

Meanwhile, another disclosure showed that the Biden campaign spent $36.9 million in June.

The Trump campaign finished June with $113 million in the bank, a bit bigger than the amount of $108.9 million held by the Biden campaign.

Data released earlier this month showed that Trump brought in $74 million in June, while Biden garnered $81 million, which marks the second consecutive month the presumptive Democratic nominee had raised more than the president.

In June, the Trump campaign funneled more than $41 million on television, digital, and other ads, buying significant television air time across the country. Those ads took shots at Biden over his age and his record on China.

Meanwhile, the Biden campaign launched the first major advertising blitz in the second half of June, targeting battleground states like Pennsylvania and Michigan. His campaign increased digital advertising spending to nearly $17 million in June from about $175,000 in May.

Biden spent less than Trump in June as the former vice president is leading in opinion polls. RealClearPolitics’ polling average shows the Democrat leading the president by 8.6 percentage points.
