(CNN) A key Republican senator said Monday he will support Judge Brett Kavanaugh's nomination to the Supreme Court.

In a series of tweets Monday morning, Kentucky Sen. Rand Paul, who had expressed some concerns about Kavanaugh's record related to privacy and the 4th Amendment, said he would vote for Kavanaugh.

"After meeting Judge Kavanaugh and reviewing his record, I have decided to support his nomination. No one will ever completely agree with a nominee (unless of course, you are the nominee). Each nominee however, must be judged on the totality of their views character and opinions," Paul said in one of those tweets.

Paul followed up his initial comment with an entire series highlighting why he was backing Kavanaugh.

"I have expressed my concern over Judge Kavanaugh's record on warrantless bulk collection of data and how that might apply to very important privacy cases before the Supreme Court," Paul tweeted. "In reviewing his record on other privacy cases like Jones, and through my conversation with him, I have hope that in light of the new precedent in Carpenter v. United States, Judge Kavanaugh will be more open to a Fourth Amendment that protects digital records and property."
