Donald Trump Teases Updates to His VP Search

He shared some tea leaves on Twitter.

He published a string of tweets praising three people who are believed to be in contention to become the presumptive GOP nominee's running mate.

The second referenced Indiana Gov. Mike Pence, who is reportedly under consideration for the job, according to a Republican source.

In a statement, Ernst said she had a "good conversation" with the presumptive GOP nominee, and said she will continue to advise Trump.

"I will continue to share my insights with Donald about the need to strengthen our economy, keep our nation safe, and ensure America is always a strong, stabilizing force around the globe," she said.

Trump will travel to Washington Thursday for meetings with House and Senate Republicans - the first time he'll face the majority of elected GOP officials in Washington, who largely dismissed his campaign in the GOP primary.

For his part, Trump didn't reveal any other names today.
