The man charged with placing two pipe bombs in# Washington, D.C., on the eve of the January 6## Capitol attack says he did so because he believed# someone needed to -- quote -- "speak up."

Returning to the war in Ukraine, President# Volodymyr Zelenskyy says the U.S.

offered## Kyiv security guarantees for 15 years# to deter Russia from returning to war## after a cease-fire.

But that's far# less than what Zelenskyy wanted,## up to 50 years of guarantees.

In a briefing# with reporters conducted via WhatsApp,## Zelenskyy said President Trump would# think about extending the time frame.

Zelenskyy added -- quote -- "Without security# guarantees, realistically, this war will not end."

Meanwhile, in the Ukrainian capital, Kyiv, at a# permanent memorial, residents shared Zelenskyy's## concern that Russian President Vladimir Putin# could resume the war even if peace were reached.

NATALIA FOMINA, Kyiv Resident (through# translator): We see our enemy.

We know## that talks don't stop him.

Only real strength can## stop him.

So it's unlikely that# these talks will stop the war.

They have been doing naval exercises,"# meaning Beijing, "in the area for 20 years."

pledged $2 billion, which the U.N.

's# emergency chief called landmark, but it's a## fraction of the money the U.S.

has historically# contributed to U.N.

agencies every year.

The U.S.

says the new funding mechanism is# an attempt to reduce bloat by funneling money## to a coordinating U.N.

agency, rather# than individual agencies like UNICEF.## Today's U.S.

pledge also came with# a threat.

Those U.N.

agencies,## the State Department said, must --# quote -- "adapt, shrink, or die."
