West Virginia’s congressional delegation in the U.S. Senate is divided over providing additional U.S. funding for Ukraine.

U.S. Senator Shelley Moore Capito, R-W.Va., said she voted against beginning debate on a funding bill for Ukraine and Israel because it didn’t include provisions for securing the southern border. U.S. Senator Joe Manchin, D-W.Va., voted in support of a motion to begin debate on Ukraine funding, arguing that Senate Majority Leader Chuck Schumer would allow border amendments to be added to a national security supplemental bill.

Ultimately, debate on the bill was blocked by Republicans, who want border security provisions to be added to a funding appropriations bill for Ukraine and Israel. Republicans in both the U.S. Senate and the U.S. House argue that the souther border is a national security issue — as millions of migrants are being allowed to enter the country illegally by the Biden administration.

Capito said lawmakers can’t achieve national security as a whole without first securing the United State’s own borders.

Capito, a member of the Senate Homeland Security Appropriations Subcommittee, says so far this year 169 individuals with positive terrorism watchlist matches tried to cross the southern border into the U.S.

Since President Joe Biden took office, Capito says 7.6 million illegal migrant encounters have occurred at the southern border, including 2 millions this year alone.

“I have said time and time again that I am supportive of a national security supplemental that assists our allies abroad, such as Israel and Ukraine, as well as the national security challenges we face here at home,” Capito said. “The border is one of those challenges.”

Capito said the funding bill put forward by Schumer made no policy changes to secure the southern border and stop the migrant crossing crisis.

Manchin disagreed, arguing Ukraine needs U.S. funding support and that Schumer would later allow border amendments.

“Common sense should dictate that we need to secure our own border in addition to helping Ukraine and Israel secure theirs,” Manchin said. “In the greatest country on Earth, we do not have to choose between protecting our homeland and defending our allies. My support for Israel and Ukraine is unwavering but it does not supersede my commitment to my own country. We need major, structural reforms to limit the number of illegal crossings at our southern border and regain operational control.”

It was not immediately clear Thursday when the U.S. Senate would attempt another vote on the Ukraine-Israel funding bill.

President Joe Biden also is demanding that humanitarian aid for Palestinians be added to the funding bill.
