First lady Jill Biden arrived at the Houston Food Bank around 1 p.m. on Friday with Texas first lady Cecilia Abbott, according to a pool report.

Biden and Abbott first stopped in the main lobby for several minutes and received a rundown of the food bank’s food distribution process from Nicole Lander, the organization’s chief impact officer. Lander told the first ladies that the food bank distributes an average of 18 million pounds of food per month during disasters, the equivalent of 20 tractor-trailer loads. Lander also noted that one in four children in the Houston area lacks consistent access to nutritious food, according to the report.

Biden and Abbott then moved to a warehouse room and joined volunteers in packing bags of food for the food bank’s Backpack Buddy program, which distributes food on weekends to students who rely on school meals during the week.

Biden packed canned peaches, while Abbott packed boxes of raisins.

They were joined by Houston Independent School District Interim Superintendent Grenita Lathan, according to the pool report.

After their first stop, Biden and Abbott moved to a separate room to pack meals for seniors through the food bank’s Senior Box program, which is funded by the U.S. Department of Agriculture and provides a monthly box of food to roughly 11,000 low-income seniors in the Houston area, a separate pool report said.

Biden packed quick oats into boxes. Abbott also helped pack food boxes nearby, wearing a face mask emblazoned with the Texas flag.

Biden toured the Harris County Emergency Operations Center in Houston as the first first stop on his trip in Texas in the wake of deadly winter storms. He was joined by Sen. John Cornyn, R-Texas, and other lawmakers and local officials.

"It’s a hell of an operation you’ve got here," Biden said upon arriving to the center.

The director of the center, Mark Sloan, detailed the operations of the facility and of the impact of the winter storms on the region. He said that of the 5 million residents in the county, the storm left 1.5 million people without power and heat and detailed the county's trouble getting water to residents, noting that approximately 3.5 million were without water. He talked about the emergency response, including handing out meals and water.

Biden thanked the workers, saying they were saving lives and "doing God's work."

In a statement shared with Congress, the Biden administration announced Friday that it is creating a new “Khashoggi policy” to impose visa restrictions on any foreign official believed to be directly involved in plots against dissidents, or any “serious, extraterritorial counter-dissident activities,” like the killing of journalist Jamal Khashoggi.

The State Department has identified 76 Saudi individuals who Secretary of State Antony Blinken says have been hit with these penalties. It’s unclear if Saudi Arabian Crown Prince Mohammed bin Salman is in that group because visas are confidential under U.S. law. But the “Khashoggi ban,” as Blinken calls it, will apply to their family members as well.

The Treasury Department has also sanctioned one former Saudi official, Deputy Intelligence Chief Ahmad Hassan Mohammed al Asiri, another close confidant of bin Salman, but one who was fired after Khashoggi’s murder. But for now, bin Salman escapes U.S. financial penalties—with many U.S. lawmakers already calling for him to face specific sanctions.

“While the United States remains invested in its relationship with Saudi Arabia, President Biden has made clear that partnership must reflect U.S. values,” Blinken said, adding the U.S. will no longer tolerate these extraterritorial plots and the State Department will begin reporting on them in its annual human rights report.

Biden was greeted on the tarmac in Texas on Friday by Gov. Greg Abbott who he fist-bumped after touching down for his first presidential disaster visit.

Biden was also greeted on the tarmac by a group of lawmakers including Democratic Texas Reps. Sheila Jackson Lee, Al Green, Lizzie Pannill Fletcher and Sylvia Garcia, as well as Houston Mayor Sylvester Turner and Harris County Judge Lina Hidalgo.

First lady Jill Biden also gave a fist-bump to Abbott and accepted a bouquet of flowers, as Biden bumped elbows with Jackson Lee and Green, who also took a photo of him. Biden stood near the two Democratic lawmakers and chatted for a few moments before moving on to speak with other elected officials.

Garland described the Jan. 6 insurrection at the Capitol as "the most heinous attack on the democratic processes I have ever seen and one I never expected to see in my lifetime." He added he will make sure to provide career prosecutors all the resources they need to carry out their investigations while also taking a broader look at the symptoms behind the country's domestic extremism problem.

Asked by Sen. Dianne Feinstein, D-Calif., whether the president "has the absolute right to do what he wants with the Justice Department," Garland said presidents are "constrained by the Constitution as are all government officials" and cited comments by Biden committing to not interfere with Justice Department matters. At the same time, Garland said that the Department of Justice is part of the executive branch and because of that, on policy matters they do "follow the lead of the president and the administration as long as it is consistent with the law." When asked who an attorney general represents when his interests conflict with the president's, Garland said the attorney general "represents the public interest, particularly and specifically as defined by the Constitution and the statutes of the United States."

Asked whether the president can order an attorney general to open or close an investigation, Garland said such a question was a hard one for constitutional law but that he did not expect it to be a question for himself given President Biden's statements assuring independence for the department.

Sen. Lindsey Graham, R-S.C., took a contentious tone with Garland in his line of questioning as he pressed him on multiple topics. At one point, when Graham asked Garland whether he thought former FBI Director Comey was a good FBI director, Garland declined to answer, which Graham said he found "stunning" because he thought Comey was terrible. Sen. Sheldon Whitehouse, D-R.I., pressed Garland on whether he would commit to investigating not only the rioters who attacked the Capitol on Jan. 6, but those "upstream" like the funders, organizers, ringleaders or others not actually at the Capitol.  Garland cited his past experience as a line prosecutor, noting "we begin with the people on the ground and we work our way up to those who are involved and further involved -- and we will pursue these leads wherever they take us."

Asked about whether he would end the Trump Justice Department's policy of generally stonewalling in the face of oversight requests from Congress, Garland committed to Whitehouse that the department would be "as responsive as possible" to any requests and "at the very least why if it can't answer a question or can't answer a letter." Garland also committed that he would work with Whitehouse on getting answers to the committee on requests that the Justice Department under Attorneys General Bill Barr and Jeff Sessions previously ignored.

In an exchange with Sen. John Cornyn, R-Texas, Garland committed that his personal politics will have no impact on prosecutions and investigations he oversees as attorney general. Asked what he would do if he was ordered to do something that he considered to be unlawful, Garland said he would first tell the president or whoever else was asking him that what they were ordering was unlawful and would resign if no alternative was accepted.

Asked by Sen. Amy Klobuchar, D-Minn., what he will do to improve morale in the department, Garland said he would on his first day make an oath to career prosecutors and agents "that my job is to protect them from partisan or other improper motives." Klobuchar then asked Garland whether he believes he'd need "additional authorities" to combat the country's domestic terrorism problem. Garland said while the department "is probably always looking for new tools ... the first thing we have to do is figure out whether the tools that we have are sufficient."
