Alabama's Senate race reached a new level on Friday.

Republican Roy Moore's campaign blocked his opponent, Democrat Doug Jones, on Twitter.

To block someone on Twitter is a mechanism available to users to prevent a particular account from following the account or viewing what is posted from the account on the social media platform.

So whatever is tweeted from Moore's campaign account, the Jones campaign account is prevented from seeing it.

The Jones campaign tweeted that it had been blocked by Moore at 4:30 p.m. Friday, combining a tweet from Jones from last month criticizing Moore with the message that Moore had blocked Jones.

In tweeting the two images, the Jones campaign captioned it: "Shot/chaser."

The Jones campaign confirmed to AL.com late Friday afternoon that it had been blocked by Moore on Twitter.

"Roy Moore is hiding from the issues, hiding from the voters, hiding from the media and now apparently hiding from us on social media," campaign spokesman Sebastian Kitchen said in a statement to AL.com.

Jones has hammered Moore in a series of media interviews this week about not discussing issues -- particularly funding for the state's child health insurance program, which is expected to be exhausted by March 2018.

The Moore campaign did not immediately respond to a request for comment.

Jones tweeted seven times on Friday directly and indirectly about Moore, including twice using the Moore campaign Twitter handle @MooreSenate. The Jones team also twice tweeted links to an AL.com column that had the headline "Where have you gone, Roy Moore?" Jones also tweeted another AL.com story about Republicans who have shifted their support to Jones.

It's the second dust-up involving Alabama politics in the past two days on Twitter - the quick-hit social media messaging format that President Trump uses daily to express his views. On Thursday, Trump twice called for the suspect charged with killing eight people by running them over in his van in New York earlier this week to receive the death penalty.

On Thursday, the Twitter back-and-forth occurred between Democrat U.S. Rep. Terri Sewell of Birmingham and Republican Alabama Secretary of State John Merrill over voting issues.

Voters go to the polls Dec. 12 to vote between Jones and Moore.
