MESA, Ariz. - Donald Trump has gone after seemingly everybody during his campaign and that extended to the Chicago Cubs and their owners earlier this week.

Trump Tweeted the Ricketts family had "a lot to hide" after discovering Marlene Ricketts gave $3 million to an anti-Trump campaign:

 

 

Major League Baseball commissioner Rob Manfred brushed aside Trump's Tweet later that day and got together with Cubs chairman Tom Ricketts Tuesday in a prearranged meeting.

As Tom Ricketts met with the media before the Cubs' first official workout Wednesday, Trump's Tweet naturally came up:

"It's a little surreal when Donald Trump threatens your mom," Ricketts said. "The fact is, whether it's my mom or my dad on his Ending Spending stuff or my sister on marriage equality or my brothers and what they do or what we do with the team, we're pretty much an open book.

"We stand up for what we believe in. We support the causes that we think are important. That's what America should be. That's who we are."

Ending Spending is the Super Pac against President Obama that Joe Ricketts - Tom's father - donated to that caused a stir back in 2012.

 

When asked what Trump might have been referring to with what the Ricketts could be hiding, the Cubs chairman shrugged.

"Look, if we had something to hide, you guys [the Chicago media] would've found it by now, I'm sure," Ricketts said. "I have no idea."
