An American politician has taken aim at Prime Minister Justin Trudeau and President Joe Biden for extending the Canada-U.S. border closure by another month.

Responding to the news, which was announced on June 18, senior Republican and New York Representative Elise Stefanik described the extension of travel restrictions as "unacceptable" and "misguided."

In an official statement shared on the same day, Stefanik went on to call out Biden for missing the opportunity at last week's G7 leaders' summit to "stand up for America and deliver a plan to safely reopen."

She went on to accuse him of "caving to Prime Minister Trudeau's incessant desire to delay [reopening the border.]"

It's not the first time the New York representative has criticized Trudeau's involvement in restarting travel between the two countries.

Earlier this month, Stefanik wrote a letter to Joe Biden urging him to begin reopening the Canada-U.S. border and "expand exemptions for families and property owners."

"Recent comments by Prime Minister Trudeau make clear that Canada is in no hurry to begin the reopening process and will make their reopening decisions without regard to U.S. interests," she told the president.

The news that travel restrictions between Canada and the United States would be extended by a month was met with criticism from other American officials too, with one congressman describing the delay as "bullsh*t."
