Mercedes Schlapp said Tuesday that Democrats want to use the issue of migrant family separation at the border as an "emotional, divisive political play" ahead of the midterm elections.

The White House senior communications adviser called such a tactic "incredibly irresponsible" and touted the immigration reform proposed by President Trump since last year.

Schlapp said that Democrats are pushing open borders and amnesty, and that the problem of family separation can be solved by closing legal loopholes.

"If we want to see significant change, we need to close those legal loopholes so that we are able to detain and swiftly remove these family units who are coming in illegally," she said.

Schlapp said that families who are separated at the border are only apart for 5 to 10 days.

"It is incredibly heartbreaking, but it is the law," she said, adding that under the current criminal system, even American citizens who commit crimes are, too, separated from their families.

She said that the Trump administration is "simply enforcing the law," and that Republicans are asking for "real reform" on the issue.

"Right now, our hands are tied," she said. "Our agents can't do their jobs effectively."

Sen. Ted Cruz (R-Texas) announced on Monday an "emergency" bill to keep migrant families together.

It would double the number of immigration judges and demand the families in question be kept together unless there was a threat of harm to children.

Schlapp also noted that there's been a 315 percent increase in illegal immigrants using children to pose as families in order to enter the country, something Department of Homeland Security Secretary Kirstjen Nielsen said on Monday.

"That is just outrageous and needs to be stopped," she said.
