Fox News' Griff Jenkins witnessed an apparent attempt by some illegal immigrants to enter the United States on Monday, as a massive migrant caravan pushes toward the southern border about 1,000 miles away.

Awaiting a border crossing attempt in McAllen, Texas, Jenkins and his camera crew saw a group -- not part of the caravan -- crossing the Rio Grande in a raft.

He said that a family was in the raft, along with a smuggler who was steering it.

"Excuse me sir, were you trying to cross into America illegally?" Jenkins called out, before the smuggler paddled to a different part of the river bank.

"We seem to have foiled this attempt," Jenkins said.

The growing caravan of immigrants from Central America continues to inch closer to the southern border and is reportedly more than a mile long.

Last week, President Trump threatened to send the U.S. military to the border to confront the incoming caravan.

Jenkins also spoke with an illegal immigrant who was aboard a second raft crossing the river that made it to the United States.

The woman, accompanied by two others and a small child, made the trek due to "the situation of Honduras."

"You cannot work there because the criminal always will get your money," she told Jenkins.
