President Donald Trump on Tuesday continued his staunch defense of zero-tolerance in the handling of illegal immigrants and charged that Democrats want aliens to "infest" the country because they see them as future voting allies.

"Democrats are the problem. They don’t care about crime and want illegal immigrants, no matter how bad they may be, to pour into and infest our Country, like MS-13. They can’t win on their terrible policies, so they view them as potential voters?" Trump tweeted as the uproar grew over children being seized and separated from their parents as they sneak over the U.S.-Mexico border.

"We must always arrest people coming into our Country illegally. Of the 12,000 children, 10,000 are being sent by their parents on a very dangerous trip, and only 2000 are with their parents, many of whom have tried to enter our Country illegally on numerous occasions," the president said in another tweet.

And for the second day in a row, he tweeted about the immigration storm currently embracing Germany, where Chancellor Angela Merkel is battling renegade members of her government who want to tighten the rules for asylum seekers who wish to enter.

"Crime in Germany is up 10% plus (officials do not want to report these crimes) since migrants were accepted. Others countries are even worse. Be smart America!" Trump said on Twitter.

He added in another tweet: “If you don’t have Borders, you don’t have a Country!”

Trump also repeated his claim that out-of-date laws are responsible for the separations of families, which are branded cruel and inhumane by politicians, religious leaders and immigration advocates.

"Now is the best opportunity ever for Congress to change the ridiculous and obsolete laws on immigration. Get it done, always keeping in mind that we must have strong border security," Trump said.
