Attorney General Jeff Sessions is taking a trip to Sacramento Wednesday and is expected to make a "major sanctuary" announcement.
The Trump administration has promised to crack down on sanctuary cities that keep local law enforcement from alerting federal immigrations agents when they release undocumented immigrants.
Things really heated up last week after Oakland Mayor Libby Schaaf warned of an immigration sweep in advance. U.S. Immigration and Customs Enforcement (ICE) said hundreds of immigrants eluded detention because of her warning.
While details about the announcement are unknown, Sessions has previously threatened to punish sanctuary cities in California, such as Sacramento and San Francisco. He has said he wants to cut off funding to jurisdictions that won't cooperate with ICE.
There is no hard line definition of what a sanctuary city is, but it generally refers to a city that limits cooperation with the federal government on immigration enforcement. California is typically seen as a sanctuary state and tends to clash with many Trump administration policies.
So, if federal funding was cut from California, what would happen?
California is one of the least federally dependent states in the country, according to a WalletHub study released last year.
The state also receives less federal dollars than most states. According to a Pew Charitable Trusts report, in the 2013-2014 fiscal year California ranked 41st out of 50 states and the District of Columbia on federal spending per person, in part, due to its young population.
Additionally, California is a donor state, meaning California provides more in tax revenue to the federal government than it receives in federal spending.
However, if federal funding were cut in California the consequences should be concerning.
The California Budget & Policy Center released their 2018-19 California Budget Perspective report this week. The non-profit organization analyzes state fiscal and economic issues.
California may not be as dependent on federal funds as other states, but more than one-third of the state's budget is made up of federal funds, according to the report.
Nearly 75 percent of the federal funding received by Californians goes to health and human services. This means programs such as CalWORKs, CalFresh, Medi-Cal, retirement benefits and housing assistance could take a hit if federal grants were cut.
Nearly 60 percent of CalFresh food assistance participants are children, older adults or people with disabilities, according to the Budget & Policy Center.
"CalFresh is one of those programs that's very critical, that helps families that are struggling to make ends meet," said Steven Bliss, director of strategic communications for the California Budget & Policy Center.
Bliss stressed, federal cuts would mainly affect families. Millions or billions of dollars could go away from these services used primarily by families.
California is already facing an affordable housing crisis and the situation would likely get worse if there were cuts to housing assistance. Additionally, federal funding helps provide subsidized childcare for parents who work and plays a role in covering families who lack health insurance. Stripping away funds, could mean taking away assistance from families living under the poverty level.
It's important to note, even if the Trump administration decides to pull the plug on funding this wouldn't mean all funding for these human and health services would just disappear overnight.
What it would do is place state policymakers "in a bind" with tough choices to make to maintain fiscal stability and support program funding, according to Bliss.
"These would be very serious cuts," said Bliss.
Sessions will make his announcement at the annual gathering of the California Peace Officers' Association in Sacramento.
