Secretary of Defense Mark Esper authorized the Pentagon on Tuesday to allocate $3.6 billion toward 11 military construction projects for President Trump's border wall, CNN reports.

The big picture: Trump is getting all the Pentagon funding that he sought — about $3.6 billion from the department's military construction fund — from declaring a national emergency over the border crisis in February. In July, the Supreme Court ruled that Trump's reprogramming of Pentagon funds for the border wall is permissible. Deputy Under Secretary of Defense Comptroller Elaine McCusker expects construction at the border to start in about 135 days, per CNN.

The other side: The ACLU said on Tuesday that it will file a motion to block the $3.6 billion from being used. The motion would fall under the Sierra Club v. Trump case put forward by the ACLU in February against the president's emergency powers declaration, but would be a "separate and entirely new motion," per ACLU spokesperson Abdullah Hasan.

Read Esper's letter:

Driving the news: Biden held a call on Ukraine this evening with the leaders of France, Germany, Italy and the U.K., while Secretary of State Tony Blinken called Ukrainian President Volodymyr Zelensky to offer America's "unwavering support."

The family of Emmett Till announced Monday that the Department of Justice has formally closed its second investigation into the 1955 murder of Emmett Till.

Why it matters: The DOJ reopened the probe in 2018 after the white woman at the center of the case reportedly recanted her allegation that Till, a Black 14-year-old, sexually harassed her prior to his murder.

Rep. Devin Nunes (R-Calif.), who serves as the top Republican on the House Intelligence Committee, will retire at the end of the year and become CEO of Trump's new media organization.

Why it matters: Nunes, once considered a moderate member of the party, became one of the fiercest defenders of former President Donald Trump throughout both of Trump's impeachments and the Intel committee's Russia investigation.
