Read my statement on the breakdown of the ceasefire in Israel and Gaza below.

“Deeply concerned and heartbroken that the ceasefire in Israel and Gaza that the Trump Administration claimed credit for securing has been violated. The Trump Administration must work immediately to bring both parties back to ceasefire negotiations, protect civilians, free the hostages, and establish a peaceful path forward.”

From our spectacular almonds and grapes, to our prunes, olives and more in #CA04 there’s a lot to celebrate on #NationalAgricultureDay. To the over 14,000 ag workers in our district who keep our agricultural community the envy of the world: Thank you!

Rep. Mike Thompson@mikethompson.house.govMar 18(source)

Unthinkable that the Administration is erasing the legacy of our country’s heroes. Pfc. Ira Hayes is one of many Native American heroes who served honorably and helped us to victory in WWII. Every veteran, regardless of party stripe, should be outraged.

Is Social Security a ‘Ponzi Scheme’?

To all retired Americans, its benefits are very real.

Rep. Mike Thompson@mikethompson.house.govMar 14(source)

FACT: Social Security is an earned benefit that allows over 153,000 residents in our district to retire and live with dignity and puts $3.4 billion into our local economy each year. Previous attempts to cut or privatize Social Security were wildly unpopular, and for good reason.

Rep. Mike Thompson@mikethompson.house.govMar 14(source)
