Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

Rep. Elise Stefanik is facing senators for her confirmation hearing to be the U.S. ambassador to the United Nations.

The ideological divide between Republicans and Democrats over the utility of global organizations has taken center stage. Stefanik zeroed in on reform.

“Our tax dollars should not be complicit in propping up entities that are counter to American interests, antisemitic or engaging in fraud, corruption, or terrorism,” she said. “We must invest in programs to strengthen our national security and deliver results to increase the efficacy of U.N. programs. We must drive reform.”

She also defended Trump's decision to withdraw from another global body: the World Health Organization.

“I support President Trump's decision to walk away from WHO,” she said, arguing it had “failed on a global stage in the Covid pandemic for all the world to see, and instead spewed CCP talking points that I believe led to not only false information, but dangerous and deadly information across the globe.”

Episcopal Church leaders on Tuesday released a letter urging Trump to "exercise mercy" in his approach to immigration policy.

While the service Trump is currently attending incorporates many faiths, the National Cathedral itself is part of the Episcopal Diocese in Washington.

"Even as we gave thanks for a peaceful transfer of power, we learned from news reports that the new presidential administration has issued a series of executive orders that are a harbinger of President Trump’s pledge to deport undocumented immigrants at a historic scale, restrict asylum, and direct other immigration actions," the church leaders wrote in a letter.

"We read this news with concern and urge our new president and congressional leaders to exercise mercy and compassion, especially toward law-abiding, long-term members of our congregations and communities; parents and children who are under threat of separation in the name of immigration enforcement; and women and children who are vulnerable to abuse in detention and who fear reporting abuse to law enforcement."

President Trump and Vice President Vance are attending an interfaith prayer service at Washington National Cathedral.

It's the first public appearance for Trump since Monday night's inaugural festivities.

First lady Melania Trump, second lady Usha Vance and Trump's children are there as well.

House Speaker Mike Johnson and Republican Rep. Mike Lawler are some of the lawmakers in attendance.

Standing alongside his cabinet ministers, Prime Minister Justin Trudeau addressed President Trump’s proposed tariffs, stating firmly that if the U.S. proceeds with the measure, Canada will not hesitate to respond in kind.

"Everything is on the table," Trudeau said adding, "We are prepared for every possible scenario."
