Tucker Carlson highlighted Wednesday how some on the left seem to be rethinking their position on immigration after the political fallout in Germany, where Chancellor Angela Merkel has faced increasing backlash over what is seen as unfettered migration into the country.

In recent comments, Hillary Clinton and John Kerry - both former secretaries of state and Democratic presidential nominees - suggested Germany and other European nations must come up with better solutions for dealing with the influx of refugees from the Middle East and Africa.

"I think Europe needs to get a handle on migration because that is what lit the flame," Clinton said last week.

"I admire the very generous and compassionate approaches that were taken by leaders like Angela Merkel, but I think it is fair to say Europe has done its part and must send a very clear message, [that] we are not going to be able to continue to provide refuge and support, because if we don't deal with the migration issue it will continue to roil the body politic."

A week before, Kerry said Europe has been "crushed under this transformation" caused by mass migration, weakening Merkel's political standing. Merkel announced recently she would give up the chairmanship of the center-right Christian Democratic Union party.

Responding on "Tucker Carlson Tonight," U.S. Ambassador to Germany Richard Grenell said Merkel had no plan in place to deal with the migration, though they had "big hearts" and wanted to help refugees.

"This is not about whether you have a heart, this is about whether or not you have a plan," he explained, adding that the U.S. and European countries must come up with a way to have an "orderly" legal immigration process.
