Conflicting reports have emerged as to whether President Donald Trump has reached a tentative agreement with the incoming Mexican administration for migrant caravan members to remain in Mexico while their asylum claims are processed in the U.S.

A group of caravan members, meanwhile, planned to march toward an entry point at San Ysidro, California, on Sunday at noon, Fox News noted on Sunday morning. (The entry point was closed earlier; the situation is fluid.)

“The Trump administration has won the support of Mexico’s incoming government for a plan to remake U.S. border policy by requiring asylum seekers to wait in Mexico while their claims move through U.S. courts, according to Mexican officials and senior members of President-Elect Andrés Manuel López Obrador’s transition team,” according to a Saturday report in The Washington Post.

A contradictory CNN report, however, also emerged; it said Mexico’s incoming government had denied the Trump administration’s new proposal.

In a pair of tweets on Saturday, the president threatened to close the southern border.

He declared that the United States’ new policy for dealing with foreign nationals illegally crossing the border is to “catch and detain.”

“No ‘releasing’ into the U.S.,” he also said.

“Would be very SMART if Mexico would stop the Caravans long before they get to our Southern Border, or if originating countries would not let them form (it is a way they get certain people out of their country and dump in U.S. No longer),” he also wrote.

“Dems created this problem. No crossings!” President Trump tweeted Sunday morning.

“If you do something wrong, you don’t tell the truth … You take responsibility for it. You don’t blame it on the other kid,” said a chuckling Sen. Amy Klobuchar (D-Minn.) two hours later on ABC’s “This Week.”

She was responding to the president’s most recent tweet by pulling from her mother’s advice on dealing with second graders.

“He should have been working with these Central American countries a long time ago to try to get to a point where we didn’t see this extraordinary amount of people coming through,” Klobuchar said snidely.

Trump has been president for 22 months.

It’s also worth noting that many Democrats, in the run-up to the 2018 midterm elections, minimized the threat of the caravan, in essence declaring it a non-issue.

“He has an opportunity here, especially with a new Congress coming in, to get this done. So it all rests in that office, on him, and he needs to get this done,” said Klobuchar of presidential decision-making about the migrant caravan.

Klobuchar added that Democrats may still consider negotiating on border wall funding — which includes funding for other border security measures, as well — in order  to avoid a government shutdown.

“This is a mob … who are intent on sabotaging our laws to get jobs. What we’re talking about here is a systematic and planned manipulation and abuse of our asylum system,” said Michelle Malkin, author and CRTV host, on Fox News Channel’s “Fox & Friends Weekend” on Sunday morning.

“Asylum laws are meant for religious and political persecution … People who are part of these thousands and thousands of migrant movements that are originating in South and Central America … have announced, essentially declared, that they are not legitimate asylees,” she added, noting that the countries through which the group travels that fail to take action are also culpable.
