(CNN) The White House has no "fresh" plan to replace the Affordable Care Act, despite the administration backing a district court ruling striking down the full law earlier this week, a senior White House official told CNN Wednesday.

However, the administration plans to submit a health care replacement to Congress this year, the chief of staff to Vice President Mike Pence told CNN's Wolf Blitzer on "The Situation Room."

"The President will be putting forward plans this year that we hope to introduce into Congress," Marc Short told Blitzer. "But, the reality is the court decision is likely not until the summer of 2020, by the time it would reach the Supreme Court."

"We don't know how they would rule," Short said. "The President has said repeatedly he would not sign any law unless it would protect pre-existing conditions."

On Monday, the Trump administration said the entire Affordable Care Act should be struck down, in a dramatic reversal . The Justice Department said in a filing with a federal appeals court that it agreed with the ruling of a federal judge in Texas that invalidated the Obama-era health care law.
