Louisiana Sen. Bill Cassidy said Thursday that "it shouldn't be hard" for Democrats to reach what President Trump is looking for on border security.

Cassidy (R) said that because of issues within migrant caravans, border security shouldn't be a hard sell to Democratic voters either.

"It shouldn't be hard to get to where the president wants to be," he said, noting that Democrats voted for $25 billion for border security earlier this year.

Cassidy also referenced how in 2006, then-Sen. Barack Obama voted in favor of the Secure Fence Act along with a number of other high-profile Democrats.

"It's not as if this is a foreign concept," Cassidy said.

President Trump tweeted Thursday that his long-proposed border wall is "desperately needed" as the partial government shutdown reached its sixth day.

Trump is seeking $5 billion for his wall, although Democrats have said they are prepared to offer $1.3 billion for "border security."

Cassidy added on Thursday that the wall funding needs to be attained "bit-by-bit."

"I think it would be nice to have a $25 billion long-term commitment, but on the other hand, this problem's not going away," he said.
