President Donald Trump appears to have a short list of six or seven as he tries to put a second justice on the U.S. Supreme Court.

Trump told reporters he met with four U.S. Supreme Court nominee candidates Monday morning and intends to meet with two or three more potential high court picks before he announces a nominee on July 9.

“I had a very, very interesting morning,” Trump said of those initial meetings.

The president is slated to announce his pick the day before he leaves for a lengthy trip to a NATO summit in Belgium, a “working visit” to the United Kingdom and a one-on-one with Russian President Vladimir Putin in Finland. Trump has said he intends to select a nominee much like Neil Gorsuch, the solidly conservative justice he nominated to fill the vacancy left by Antonin Scalia’s death.
