Department of Homeland Security Secretary Jeh Johnson today used the growing border crisis to pressure House Republicans to pass the Senate immigration rewrite that is backed by President Obama.

He said that current immigration law is unstable because the GOP-majority House may approve the Senate’s complex bill, but that approval of the massive rewrite add extra resources “as well as stability in the law right now.”

“If Congress acts, I believe we would know our immigration law landscape for years, if not decades,” he said at an afternoon press conference.

Johnson made that claim even though current immigration law has been on the books for decades and the Senate’s huge bill would create sweeping changes in that law, changes that have yet to be tested in the courts.

He also used the conference to to deliver conflicting messages to two other critical audiences.
